So when you use --enable-languages=ada it says:
configure: error: GNAT is required to build ada
And with --enable-languages=d:
configure: error: GDC is required to build d
That comes from this bit in the top-level configure.ac:
# Disable Ada if no preexisting GNAT is available.
case ${add_this_lang}:${language}:${have_gnat} in
yes:ada:no)
# Specifically requested language; tell them.
AC_MSG_ERROR([GNAT is required to build $language])
;;
all:ada:no)
AC_MSG_WARN([GNAT is required to build $language])
add_this_lang=unsupported
;;
*:ada:no)
# Silently disable.
add_this_lang=unsupported
;;
esac
# Disable D if no preexisting GDC is available.
case ${add_this_lang}:${language}:${have_gdc} in
yes:d:no)
# Specifically requested language; tell them.
AC_MSG_ERROR([GDC is required to build $language])
;;
all:d:no)
AC_MSG_WARN([GDC is required to build $language])
add_this_lang=unsupported
;;
*:d:no)
# Silently disable.
add_this_lang=unsupported
;;

have_gnat and have_gdc are set by ACX_PROG_GNAT and ACX_PROG_GDC
defined in config/acx.m4 and called earlier in configure.ac.
Cheers,
