Changes to kernel code (from memory, I am at work - BSD system at home):
1 Change in ../../i386/*/npx.c the lines it comlains about to use "m"
instead of "g" - you will see what I mean when you look at it.
2 Errors also include the warning about incompatible declarations (whatever)
of strlen() in ../../sys/systm.h (comment it out - works ok).
../../i386/??/math_emulate.c line 614 need changing from:
tmp = & (long)REG(...)
to
tmp = & REG(...)
as casting makes gcc-2.2.2 & operator barf (not too suprising really).
3 ../../i386/??/pccons.c needs "=" signs added to array declarations. Try
compiling it and you will see the line numbers. Also there are a couple
of comments like "?* NNN */" the need the "?" changed to "/" (this may
be bit rot :-)
What else ? I can't remember...
*but* I have rebuilt the kernel using gcc-2.2.2 and it is *bigger* binary
wise than the one built using 1.39, and of course doesn't work :-(
gcc-2.2.2 carries around lots of redundent c++ stuff, and makes a call
to ___main (__main in libgcc2.c) which does c++ stuff. I have tried using
-fno-builtin to no avail. When I get the portable up and running (soon,
please :-) I will be able to investigate further, by which time the patches
should be out :-) :-)
Sigh. One day.
