* build: detect overflow for [re]allocate_array.Explorer092017-01-24
| | | | | | | | | | | Use reallocarray() when we have it (i.e. in OpenBSD system). When we don't, use equivalent overflow detection for our allocate_array and reallocate_array functions. Remove lib/reallocarray.c from our LIBOBJS as we no longer need it. Provide a fallback SIZE_MAX macro definition in flexint.h (not preprocessor friendly, but enough for our reallocate_array use case).
* move flex program sources into src/ directoryWill Estes2014-02-16
The *.[chly] sources are now in the src directory. This implies a bunch of changes in Makefile.am and friends to account for the new location. The .gitignore files are now more local to places where various object files and generated source files occur.
