It seems that most of those symbols are defined in the source
code and the built module ndisapi, so either they are not
properly exported as new kernel capabilities (or imported
by bcmndis) or, in more cases, the ndisapi module fails to
load - likely due to those relocations you've noticed.

One suggestion I found in the internet was to try -mcmodel=large
and my OI's gcc-3.4.3 compiler said it is not yet supported. Duh.

I added il-gcc-444 (from Rich Lowe's tarball of 2012) and mpfr
and gmp libraries as that wanted, and tried to recompile the
project with gcc-444. It had a lot more warnings about function
declarations and even fatal conflicts that gcc-343 did not care
to find or report. Very weird.

I attach my current makefile (also automates creation of ndis.sys
and ndis.inf from Broadcom files) and the gcc-444 build log, just
in case you make more sense out of it.

In reality I'm more looking forward to trying your rework based
on ndis-1.2.6 as it seems to implement more of those "missing"
functions, indeed. Further on, maybe, some text would have to
be snatched from FreeBSD's compat/ndis sources ;)
