Odd. Here's the advertised behaviour in egcs-1.1 and what I see as well:
  
  % gcc -o foo.bin foo.c
  % ls foo.bin
  foo.bin
  % ./foo.bin
  Foo here
  %

What is the general consensus, if any, here? Here're the choices:
  
  1. add .exe never.
     [ gcc -o foo [...]     ==> foo ]
     [ gcc -o foo.exe [...] ==> foo.exe ]
     [ gcc -o foo.bin [...] ==> foo.bin ]
  2. add .exe always, unless .exe is already there. 
     [ gcc -o foo [...]     ==> foo.exe ]
     [ gcc -o foo.exe [...] ==> foo.exe ]
     [ gcc -o foo.bin [...] ==> foo.bin.exe ]
  3. add .exe only if no suffix is provided.
     [ gcc -o foo [...]     ==> foo.exe ]
     [ gcc -o foo.exe [...] ==> foo.exe ]
     [ gcc -o foo.bin [...] ==> foo.bin ]

I lean towards 3, which is what's implemented -- it follows conventional 
wisdom on this particular platform, doesn't screw up native shells and 
other tools that expect executables to .exe (unless you explicitly want 
some other extension), and it has the added benefit of being compatible 
with how the native compilers work.
