"g77 -mno-cygwin" will most likely call
/usr/lib/gcc-lib/i686-pc-mingw/3.3.1/f771.exe, which should be part of the
"gcc-mingw" package.  Unfortunately, "gcc-mingw" uses a weird packaging
scheme (a tarball inside a tarball), so you couldn't have used the package
search page to find that out.  Judging by the size of the tarball in the
latest "gcc-mingw-20030911-2" package (1.3M) vs. the one in 20020817-5
(2.1M), some files may be missing in the new version.  It's likely
f771.exe is one of them.  If you have the latest "gcc-mingw" installed,
"tar tf /etc/postinstall/gcc-mingw-3.3.1-20030804-1.tar | grep f77" should
confirm or deny my guess.
