BTW, I just improved the perl API concerning Win32 case-tolerance.

perldoc File::Spec

Cygwin
Cygwin case-tolerance depends on managed mount settings and as with 
MsWin32 on GetVolumeInformation() ouFsFlags == FS_CASE_SENSITIVE, 
indicating the case significance when comparing file specifications.
Default: 1

MsWin32
MSWin32 case-tolerance depends on GetVolumeInformation() ouFsFlags == 
FS_CASE_SENSITIVE, indicating the case significance when comparing file 
specifications.
Since XP FS_CASE_SENSITIVE is effectively disabled for the NT subsubsystem.
See http://cygwin.com/ml/cygwin/2007-07/msg00891.html
Default: 1

Interestingly:
Epoc, VMS, OS2 and Mac are all case tolerant, too.
