Hi All,

I'm having a problem with cygwin make and the $(wildcard) function.  I've
attached a Makefile which demonstrates the problem.  The gnu make
documentation indicates that the wildcard function should only return files
or directories that exist, but in certain circumstances it is returning
paths that do not exist.  This appears to be a bug introduced in the base
cygwin package.  Specifically,

using base/cygwin 1.5.19-4:
- fails when building from linux samba share (version 3.0.20)
- fails when building from solaris samba share (version 2.2.8a)
- succeeds when building from local hard drive

using base/cygwin 1.5.18-1:
- succeeds when building from linux samba share (version 3.0.20)
- succeeds when building from solaris samba share (version 2.2.8a)
- succeeds when building from local hard drive

I've tried a number of combinations to try to eliminate the failure when
using 1.5.19-4 and the samba share:
- fails when running directly from the share in a bash shell
  (//machine/path/to/test)
- fails when running from a mounted drive in a bash shell
  (//cygdrive/g/path/to/test)
- fails when running from a mounted drive in a dos cmd shell
  (g:\path\to\test>)

I've pasted below an example run that demonstrates the failure.

Any suggestions on whether I'm doing something wrong or if this is a known
issue?  In searching on google, I saw a few similar reports, but no
resolution.  I've been working around this issue for several months now
using the old cygwin package, but several of my coworkers are seeing it now
also and I'd like to get the real issue fixed.

Thanks,
Ken
