Get "Access is denied" when trying to compile with g++ from command line. Cygwin

I just deleted gcc and g++ and renamed the g++/cc-4.

Because c:\cygwin\bin\gcc.exe isn't an executable file, it's a cygwin symbolic link.

$ file /bin/gcc
/bin/gcc: symbolic link to `/etc/alternatives/gcc'
$ file /etc/alternatives/gcc
/etc/alternatives/gcc: symbolic link to `/usr/bin/gcc-4.exe'

The underlying file runs just fine.

C:\cygwin\home\Ben>gcc-4 --version
gcc-4 (GCC) 4.5.0
