I tried to make this argument four or five years ago. The auto-extension was
introduced in B18. It is actually ld that creates the file name with the
extention and gcc is passing along a switch to cause the .exe extention to
happen. Even in the native version I can use ld directly and get foo not
foo.exe for -o foo.
If you `gcc -o run. tst.c' no extention is created as gcc thinks there already
is one. Mo, you should check to make sure that you didn't do this.
