The code uses ISO C99 strrchr() and BSD/GNU setenv(), but you'll
probably want Cygwin for the all the Unix functions (getpwuid(),
execv(), fork(), etc.) anyway.

I just did "make shell". :-)

Yes, I put it in /bin and changed c:/cygwin/cygwin.bat to use that
instead.  You can put it /usr/bin of even / if you prefer.

It's a trivial program I wrote with reference to no other programs.  I
hereby release it into the public domain.  Use it as you like.
