How do you test to see if the compiler supports a given option?

Specifically, gcc -municode

i would do that:

CFLAGS_save="${CFLAGS}"
CFLAGS="${CFLAGS} -municode"
AC_COMPILE_IFELSE(
   [AC_LANG_PROGRAM([[]])],
   [have_unicode="yes"],
   [have_unicode="no"])
AC_MSG_CHECKING([whether the compiler supports -municode])
AC_MSG_RESULT([${have_unicode}])
CFLAGS="${CFLAGS_save}"
