  And by a link.

  Nope, of course not.  Use "gcc-3.exe" instead.

  You mean /etc/alternatives, I think.

  That didn't work when I tried it:

C:\cygwin\etc\alternatives>gcc
Access is denied.

C:\cygwin\etc\alternatives>gcc.lnk
Access is denied.

C:\cygwin\etc\alternatives>

  GCC doesn't do that sort of thing.  What actual command do you type, and
what symptom do you get?  What program is running if you check with "ps -a" in
another window while this possible wait-to-press-enter is occurring?  Does GCC
go ahead and generate a compiled output after you press enter?

  The problem arises because you insist on two things: 1) you want to use
cmd.exe, 2) you want to start a program without typing the name it's actually
called.  Since cmd.exe doesn't understand links, your two requirements are
mutually contradictory.  The best solution is to downgrade, or to copy
gcc-3.exe to gcc.exe and get rid of the link stuff altogether.

    cheers,
      DaveK
