I know.  That was my point.  On other systems it's called a.out, on
Cygwin it's called a.exe.  So, if you try to learn C using the good old
K&R book from 1983, you're asked to compile hello.c and then call a.out.
Doesn't work on Cygwin for obvious reasons.  Why on earth didn't the GCC
folks decide to name the output file a.out.exe, so you can run "hello,
world" by running a.out as well?
