Consistently make use of the ANSI C function definition style instead of
the K&R style.
|
| |
|
|
|
|
| |
Assuming a compiler conforming to the ISO C standard is used, i.e.,
__STDC__ is defined to 1, YY_USE_CONST is always defined and can be
eliminated.

As with flex_alloc(), replace calls to flex_realloc(), which was just a
wrapper around realloc().

The function flex_alloc() was just a wrapper around malloc(). Since this only added unclarity, and the flex_alloc() function is likely a legacy of olden times, remove it in favor of calls to malloc() directly.
Style elements cleaned up:
* superfluous spacing around parentheses
* non-constant initialization in variable declarations
* needless casts
* almost all uses of assignments as subexpressions

Like copy_string(), copy_unsigned_string() is just a clone of the
stlib's strdup(). We only use it twice. I'm pretty confident that char
signedness is irrelevant in this case.

copy_string() was a clone of the stdlib's strdup(). For safety,
simplicity, and speed, we should use that instead. We introduce xstrdup() which wraps strdup() in a failure upon memory allocation errors.

Thanks to Michael McConville for pointing out that the old Char macro
causes problems with static analysis. The macro has been removed and
replaced with 'unsigned char' throughout the flex sources. The macro is
not needed at best and was confusing at worst. It was not used in any of
the example files nor was it mentioned in the manual at all.

flex was using K&R function definitions for some functions and
ANSI C style in others, sometimes even in the same file. Change
the code to consistently use ANSI C.

const fixes.
-Wconversion fixes for the skeleton files.
param namespace protection (add _ to inline function parameters).
unused variable/code removal.
rename warn to lwarn to avoid conflict with <err.h>.
ctype.h function argument correction.
merged the error functions lerrif and lerrsf -> lerr.

clang-3.5.0 now complains about them: warning: 'register' storage class specifier is deprecated [-Wdeprecated-register]

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.
