Actually, even "fsdb hello" will work, provided that there is a file
`hello' in that directory.  But many users say "gcc -o hello.exe",
which only creates `hello.exe'.  If you say "gcc -o hello", that would
produce both `hello' and `hello.exe', and "fsdb hello" will work.

Note that chapter 12 in the FAQ explicitly tells you to say "gdb foo.exe".

Patches to fsdb to make it look for .exe are welcome.
