Well, I've had it happen again. Details below.

This is my CYGNUS.BAT:

@ECHO OFF
SET MAKE_MODE=UNIX
SET PATH=E:\gcc-2.95.1-mingw32\bin;E:\gcc-2_95-mingw32\bin\;E:\cygnus\cygwin-b20\H-i586-cygwin32\bin;%PATH%
SET CDPATH=
SET HOME=/home
SET CYGWIN=ntsec
bash --login

This is the 'Path' system environment var definition:

E:\Perl\bin;%SystemRoot%\system32;%SystemRoot%;F:\Programme\Personal Communications;f:\aintx;%SystemRoot%\system32\nls\ENGLISH;%SystemRoot%\system32\nls;E:\NTReskit

The first (and second) Cygwin window opened today had the 
following PATH:

PATH='/Perl/bin:/WINNT/system32:/WINNT:/f/Programme/Personal Communications:/f/aintx:/WINNT/system32/nls/ENGLISH:/WINNT/system32/nls:/NTReskit:/cygdrive/w/:/cygdrive/z/:/cygdrive/y/:/cygdrive/x/'

Then I added an empty user environment var PATH, and lo and 
behold, the next Cygwin window opened had:

PATH='/gcc-2.95.1-mingw32/bin:/gcc-2_95-mingw32/bin/:/cygnus/cygwin-b20/H-i586-cygwin32/bin:/Perl/bin:/WINNT/system32:/WINNT:/f/Programme/Personal 
Communications:/f/aintx:/WINNT/system32/nls/ENGLISH:/WINNT/system32/nls:/NTReskit:/cygdrive/w/:/cygdrive/z/:/cygdrive/y/:/cygdrive/x/:/cygdrive/c/WIN95.US:/cygdrive/c/WIN95.US/COMMAND:/cygdrive/c/WIN98.US/COMMAND:/cygdrive/c/WIN98:/cygdrive/c/WIN98/COMMAND:/f/READIBMW:/f/vim/vim55'

So: absence of this variable does not always produce the bug, but 
*if* the bug shows up, creating said variable removes it.
