Re: [Oorexx-devel] RFE 1711398, SysFileTree Case independent filename matching

[David A. <da...@us...>]

I looked this up on the Solaris VM I have installed on the build machine. 
Only the POSIX options are mentioned on the Solaris man page. So I think 
we have to leave in your code as-is.

Maybe we should hold off on adding this for now. My concern is that, since 
the fnmatch* APIs are not ANSI standard then they may not be included in 
every *nix distribution. Are we certain that these are included in all 
*nix distributions we want to support? 
 
I looked into this a little more.  I think fnmatch() is probably pretty 
standard, it looks like it is POSIX.  But fnmatchcase() is not standard, 
it is not on any of my Linux boxes.

CONFORMING TO
       ISO/IEC  9945-2: 1993 (POSIX.2).  The FNM_FILE_NAME, 
FNM_LEADING_DIR, and FNM_CASEFOLD flags are
       GNU extensions.

fnmatch does have a caseless option, but it looks like it is a GNU 
extension
only - not POSIX.
#if !defined _POSIX_C_SOURCE || _POSIX_C_SOURCE < 2 || defined _GNU_SOURCE
# define FNM_FILE_NAME  FNM_PATHNAME /* Preferred GNU name.  */
# define FNM_LEADING_DIR (1 << 3) /* Ignore `/...' after a match.  */ 
# define FNM_CASEFOLD  (1 << 4) /* Compare without regard to case.  */
# define FNM_EXTMATCH  (1 << 5) /* Use ksh-like extended matching. */
#endif

Since I already did the work, I think it might be best to leave the 
caseless code in.  Unless, others think we can rely on the GNU extensions 
being present?  I'm not too knowledgable in that area.  I think all Linux 
OSes will probably have the GNU extensions, but I'm not sure about Solaris 
or AIX.
