Re: Should I be able to build cross gcc 4.x on Cygwin?

How can i get the combined build to not build multilib versions of

The weirdest thing here is this "reinventing the wheel" !
I understood newlib already being built for the $target on MacOS X. But
for some very peculiar reason it should be reproduced for just
the same $target on Cygwin....
What will happen next ?
o the results will be compared, file by file and if there is any
difference, one of the produced GCCs outputs bad code... But which one?
This can be a good test for the "equivalency" or "similarity" of
the two GCCs on different hosts.
o the results will NOT be compared, any differences are taken as "host
dependencies", of course a Cygwin-hosted GCC produces
different code for the $target than a MacOS X hosted one... (Does
someone really believe this?)
What will the up-to-date "software engineering" books say about this
wheel-reinvention? I read my "Pressman" ("A practitioner's approach")
over 10 years ago, so I don't remember any advices for reinventions in
these things :(
I myself would TRUST that newlib done on MacOS X and would keep ONLY
that on both hosts. If some day there would be some
bugs found, the MacOS X hosted GCC would be sued or the newlib
sources.... Maybe then trying the Cygwin hosted GCC to produce
the same newlib sources would come in question.
