Cygwin gcc "access denied"

 cygwin gcc outputs "access denied" then called from cmd.exe. The reason for the problem is described in this post. Basically it because cygwin uses symbolic links for configuration of gcc to point at gcc-3.exe or gcc-4.exe and windows don't understand symbolic links. So I will have to replace my calls to gcc.exe with gcc-4.exe to make it work from cmd.exe.
