Eli,

OK, I got the latest beta of BASH, and read the README.DOS file as
well as the BASH man text, but I am somehow not getting the rules for
the BASH PATH variable right.  As a simple example, I set PATH in the
BAT file I use to invoke BASH, then just try to execute the simple
pipe "set | less" with that PATH.  It does not find "less", which *is*
in "/bin", and "/bin" *is* in the PATH.  If I then reset PATH to
*just* "/bin", the "set | less" pipe works, but if I set it to
".:/bin" it does *not* work.

I am using PATH_EXPAND=Y and PATHSEPARATOR=: in the BAT file, and I
set SYSROOT as well.  I also used your suggestion of "ln -s bash.exe
sh.exe" to create a "sh.exe" in /bin.

Below are the contents of the BAT file I used, and the contents of the
"set > file" commands I execute at several points to record the
current variables.  Any info or advice on what I'm doing wrong would
be greatly appreciated.
