configuring with non-standard location of gcc

[Maynard Johnson]

Hi,
I'm working on a project that uses autoconf/automake.  Currently, the 
configure.in defined for this project has a "--with-gcc" option that was added 
back in 2005 to allow specifying the location of the compiler to use.  I'm 
doing some cleanup of our configure script and have found that this option 
simply doesn't work since our use of AC_PROG_CC is being executed prior to the 
"--with-gcc" option, even though the configure.in has the "--with-gcc" option 
first.  In my investigation of this issue, it seems to me that the "--with-gcc" 
option is not a valid method for setting CC, and that users should pass 
"CC=blah" to ./configure instead.  Is that correct?

Thanks.
