@item --enable-stage1-languages=@var{lang1},@var{lang2},@dots{}
Specify that a particular subset of compilers and their runtime
libraries should be built with the system C compiler during stage 1 of
the bootstrap process, rather than only in later stages with the
bootstrapped C compiler. The list of valid values is the same as for
@option{--enable-languages}, and the option @code{all} will select all
of the languages enabled by @option{--enable-languages}. This option is
primarily useful for GCC development; for instance, when a development
version of the compiler cannot bootstrap due to compiler bugs, or when
one is debugging front ends other than the C front end. When this
option is used, one can then build the target libraries for the
specified languages with the stage-1 compiler by using @command{make
stage1-bubble all-target}, or run the testsuite on the stage-1 compiler
for the specified languages using @command{make stage1-start check-gcc}.
@item --disable-libada
Specify that the run-time libraries and tools used by GNAT should not
be built. This can be useful for debugging, or for compatibility with
