"gcc -v --help "  should list all options that your gcc supports (to
stderr on my system).

so use
"gcc -v --help > options.lst  2>&1"

and check if  -no-cpp-precomp is in options.lst.


What I know of autoconf/configure is dangarous. Best  if you check with
the people who developed  autoconf  (They should be able to give you the
Best advice ).
