Subject: arc profiling: output fails with -mno-cygwin
Mime-Version: 1.0
Content-Type: text/plain; charset=ISO-8859-1

My executables compiled with -fprofile-arcs and -mno-cygwin fail to
output the profiling information. I include, below, a sample session
illustrating my program. The first "a.exe" creates "main.da" okay. The
second doesn't. Can you help?

Regards,
Richard Copley.
