To fix this, we use the GNU regex library which is already present in
the compat/ diretory for the MinGW port. However, simply adding compat/
to the COMPAT_CFLAGS variable causes a conflict between the system
fnmatch.h and the one present in compat/. To remedy this, move the
regex and fnmatch functionality to their own subdirectories in compat/
so they can be included seperately.
I wonder if this is the right fix? Right now the GNU regex library is
necessary for Darwin, FreeBSD and AIX. I can add IRIX6.5 and Solaris 7
to that list. Have newer Solaris's been tested yet? (Jeff?) I wonder if
the new test which triggers this flaw has been tested on the other
non-GNU platforms in the Makefile which have not been updated. Boyd
Lynn Gerber and his 12 platforms comes to mind.
It seems POSIX only mentions alternation under Extended Regular Expressions.
Likewise for the vertical-line character '|'.
Someone forwarded me this email and asked if I had tested it. I have not.
Where is the easiest place to get it to test with the various platforms?
I will check it out on 3-5 of them. I now have 1.6.0.2 on 5 platforms
running and working. I have not had the time to get it on the other's
yet.
