Apart strict-aliasing warnings, fix the remaining warnings generated by GCC 4.4.4 -Wall and -Wextra flags. One major source of warnings was the in-house function my_bcmp which (unconventionally) took pointers to unsigned characters as the byte sequences to be compared. Since my_bcmp and bcmp are deprecated functions whose only difference with memcmp is the return value, every use of the function is replaced with memcmp as the special return value wasn't actually being used by any caller. There were also various other warnings, mostly due to type mismatches, missing return values, missing prototypes, dead code (unreachable) and ignored return values. |

See WHATSNEW for change listing.
installation notes:
--------
Read the comments at the beginning of Makefile before running.
Utils.h contains some things that just might have to be modified on
some systems, as well as a nested include (ugh) of <assert.h>.
The "fake" directory contains quick-and-dirty fakes for some header
files and routines that old systems may not have. Note also that
-DUSEBCOPY will make utils.h substitute bcopy() for memmove().
After that, "make r" will build regcomp.o, regexec.o, regfree.o,
and regerror.o (the actual routines), bundle them together into a test
program, and run regression tests on them. No output is good output.
"make lib" builds just the .o files for the actual routines (when
you're happy with testing and have adjusted CFLAGS for production),
and puts them together into libregex.a. You can pick up either the
library or *.o ("make lib" makes sure there are no other .o files left
around to confuse things).
Main.c, debug.c, split.c are used for regression testing but are not part
of the RE routines themselves.
Regex.h goes in /usr/include. All other .h files are internal only.
