[DotGNU]Warning: a.out.exe changed to a.out

[Rhys Weatherley]

I have modified the CVS version of cscc so that the default executable name is 
"a.out" under Unix or "a.exe" under Win32, rather than "a.out.exe".

This change is to make cscc consistent with gcc so that autoconf/automake 
scripts don't get confused by the odd default output filename.

So, if like me you are used to running "ilrun a.out.exe" after "cscc blah.cs", 
you will now need to use "ilrun a.out" or "ilrun a.exe" instead.

Cheers,

Rhys.
