I'm having a look at building GCC with OpenWatcom to reduce build
times. There seems to be something wrong with the build machinery:
Can you try this patch? RANLIB_FOR_BUILD was defined nowhere, hence it
was passed as empty to configure and detected (incorrectly) to be
ranlib instead of owranlib.
This dates back more or less to the dawn of time^Whaving a separate
directory for build-side libraries
(http://gcc.gnu.org/ml/gcc-patches/2001-11/msg01576.html). This evolved
into more complete support over time (including e.g. building
flex/bison/texinfo that can be used when building other tools, which in
turn evolved into toplevel fixincludes), but this bit was always missing.
(It might even be that it worked with Cygnus configure, and stopped
working after autoconfiscation).
If it works, feel free to apply it.
