Now supports Berkeley DB versions >= 4.1 in addition to 1.x. The versions inbetween are not supported because they require code changes and I don't have them available to test against.

+dnl @synopsis AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
+dnl
+dnl This macro compares two version strings. It is used heavily in the
+dnl macro _AX_PATH_BDB for library checking. Due to the various number
+dnl of minor-version numbers that can exist, and the fact that string
+dnl comparisons are not compatible with numeric comparisons, this is
+dnl not necessarily trivial to do in a autoconf script. This macro
+dnl makes doing these comparisons easy.
+dnl
+dnl The six basic comparisons are available, as well as checking
+dnl equality limited to a certain number of minor-version levels.
+dnl
+dnl The operator OP determines what type of comparison to do, and can
+dnl be one of:
+dnl
+dnl eq - equal (test A == B)
+dnl ne - not equal (test A != B)
+dnl le - less than or equal (test A <= B)
+dnl ge - greater than or equal (test A >= B)
+dnl lt - less than (test A < B)
+dnl gt - greater than (test A > B)
+dnl
+dnl Additionally, the eq and ne operator can have a number after it to
+dnl limit the test to that number of minor versions.
+dnl
+dnl eq0 - equal up to the length of the shorter version
+dnl ne0 - not equal up to the length of the shorter version
+dnl eqN - equal up to N sub-version levels
+dnl neN - not equal up to N sub-version levels
+dnl
+dnl When the condition is true, shell commands ACTION-IF-TRUE are run,
+dnl otherwise shell commands ACTION-IF-FALSE are run. The environment
+dnl variable 'ax_compare_version' is always set to either 'true' or
+dnl 'false' as well.
+dnl
+dnl Examples:
+dnl
+dnl AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8])
+dnl AX_COMPARE_VERSION([3.15],[lt],[3.15.8])
+dnl
+dnl would both be true.
+dnl
+dnl AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8])
+dnl AX_COMPARE_VERSION([3.15],[gt],[3.15.8])
+dnl
+dnl would both be false.
+dnl
+dnl AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8])
+dnl
+dnl would be true because it is only comparing two minor versions.
+dnl
+dnl AX_COMPARE_VERSION([3.15.7],[eq0],[3.15])
+dnl
+dnl would be true because it is only comparing the lesser number of
+dnl minor versions of the two values.
+dnl
+dnl Note: The characters that separate the version numbers do not
+dnl matter. An empty string is the same as version 0. OP is evaluated
+dnl by autoconf, not configure, so must be a string, not a variable.
+dnl
+dnl The author would like to acknowledge Guido Draheim whose advice
+dnl about the m4_case and m4_ifvaln functions make this macro only
+dnl include the portions necessary to perform the specific comparison
+dnl specified by the OP argument in the final configure script.

+dnl @synopsis AX_PATH_BDB([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
+dnl
+dnl This macro finds the latest version of Berkeley DB on the system,
+dnl and ensures that the header file and library versions match. If
+dnl MINIMUM-VERSION is specified, it will ensure that the library found
+dnl is at least that version.
+dnl
+dnl It determines the name of the library as well as the path to the
+dnl header file and library. It will check both the default environment
+dnl as well as the default Berkeley DB install location. When found, it
+dnl sets BDB_LIBS, BDB_CPPFLAGS, and BDB_LDFLAGS to the necessary
+dnl values to add to LIBS, CPPFLAGS, and LDFLAGS, as well as setting
+dnl BDB_VERSION to the version found. HAVE_DB_H is defined also.
+dnl
+dnl The option --with-bdb-dir=DIR can be used to specify a specific
+dnl Berkeley DB installation to use.
+dnl
+dnl An example of it's use is:
+dnl
+dnl AX_PATH_BDB([3],[
+dnl LIBS="$BDB_LIBS $LIBS"
+dnl LDFLAGS="$BDB_LDFLAGS $LDFLAGS"
+dnl CPPFLAGS="$CPPFLAGS $BDB_CPPFLAGS"
+dnl ])
+dnl
+dnl which will locate the latest version of Berkeley DB on the system,
+dnl and ensure that it is version 3.0 or higher.
+dnl
+dnl Details: This macro does not use either AC_CHECK_HEADERS or
+dnl AC_CHECK_LIB because, first, the functions inside the library are
+dnl sometimes renamed to contain a version code that is only available
+dnl from the db.h on the system, and second, because it is common to
+dnl have multiple db.h and libdb files on a system it is important to
+dnl make sure the ones being used correspond to the same version.
+dnl Additionally, there are many different possible names for libdb
+dnl when installed by an OS distribution, and these need to be checked
+dnl if db.h does not correspond to libdb.
+dnl
+dnl When cross compiling, only header versions are verified since it
+dnl would be difficult to check the library version. Additionally the
+dnl default Berkeley DB installation locations /usr/local/BerkeleyDB*
+dnl are not searched for higher versions of the library.
+dnl
+dnl The format for the list of library names to search came from the
+dnl Cyrus IMAP distribution, although they are generated dynamically
+dnl here, and only for the version found in db.h.
+dnl
+dnl The macro AX_COMPARE_VERSION is required to use this macro, and
+dnl should be available from the Autoconf Macro Archive.
+dnl
+dnl The author would like to acknowledge the generous and valuable
+dnl feedback from Guido Draheim, without which this macro would be far
+dnl less robust, and have poor and inconsistent cross compilation
+dnl support.
