Widening to cvs-ghc, because there are autoconf-savvy folk there.

I added the AC_PATH_PROG call to configure.ac, but I have no idea how it
works; I just copied other places.  So I hope one of you can help Norman

| 
| Gentlemen,
| 
| In fptools/ghc/configure.ac, I have found the following lines:
| 
| dnl ** Which C-- compiler to use?
| dnl --------------------------------------------------------------
| AC_PATH_PROG(WhatCmmIsCalled,qc--)
| 
| 
| I would like to modify these lines to get GHC to use qc--.opt if
| qc--.opt is available, and to use qc-- otherwise.  But I have no idea
| what is going on here or how AC_PATH_PROG works.  Would it help to
write
| 
| 
|    AC_PATH_PROG(WhatCmmIsCalled,[qc--.opt qc--])
| 
| 
| ?
| 
| 
| Norman
