Subject: New 1.3.4-blocking problem: execvp causes $0 to contain
windows path instead of Unix path
Mime-Version: 1.0

Content-Type: text/plain; charset=US-ASCII

Save the enclosed files in a directory.  Run "gcc -o execvp
execvp.exe" in that directory.  Then run "<dir>/".  It
should print "../../src/configure", but instead it'll print a Windows
path, starting with a drive letter and containing backslashes and

If you change execvp.c so that it uses "execv" instead of "execvp" and
then recompile it, the output of the test script will be correct.

This broke between the 20011020 snapshot and the 20011024 snapshot.

I will investigate more this afternoon, but not for the next few hours
(I have a meeting which I need to prepare for and attend), if somebody
else doesn't beat me to it.
