Subject:	arc profiling: output fails with -mno-cygwin
Mime-Version:	1.0
X-MIME-Autoconverted:	from quoted-printable to 8bit by delorie.com id j4L1HN5g028113

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.
