# When $CC foo.c -o foo creates both foo and foo.exe, autoconf picks
# up the foo.exe and sets exeext to .exe. That is correct for cygwin,
# which has some kind of magic link from foo to foo.exe, but not for
# rntcl. A better check for the cygwin case would check if the
# contents of foo and foo.exe are equal; in the rntcl case, foo is a
# sh script, and foo.exe is a windows executable.
