Hah!  That was not too bad - just avoid having the script try to 
figure out which C compiler is being used: TELL it to use gcc
by setting the CC env var before running configure. ;)

OTOH, since the spot where the trouble starts looks like

   touch conftest.c
   CC=$($CAMLC -verbose -c conftest.c 2>&1 | sed 's/^+ \([^ ]*\) .*$/\1/')
   echo OCaml uses $CC to compile C files

and this ends up spitting out

"OCaml uses gcc `-mcpu=' is deprecated. Use `-mtune=' or '-march=' 
instead. to compile C files"

WITHOUT OCaml saying to use this option on its constructed command 
lines, then "-mcpu=..." is being pulled from *somewhere*.  Sigh.

So the "make all" and "make opt" proceed almost normally - other than 
the C compiles having this "deprecated" warning all the time.
