[Bug-gnubg] (compile) error: 0.90* and latest SNAPSHOTs won't build with 3d-board on gentoo

[Mitch Mitchum]

Dear gnubg-mailing-list,

Since this is my first post, hello everybody.

i played gnubg for over a year on an intel-mac and admire the program.
However, i am now trying to compile gnubg on a ppc with gentoo and i can't get 
the 3d-board running.
I would love to run some 0.90* with 3d. Maybe you know of something that i 
might try.

This is what i got:

- USE-flag "opengl" is set and glxgears works fine, but the latest 
gentoo-ebuild (gnubg-14.3) and opengl won't work and seems buggy.

I then did emerge all dependencies (incl. ftgl and gtkglext) for 14.3-ebuild 
and tried to build 15.*, 0.90* and latest SNAPSHOT by configure/make/make 
install.

- stable 15.* builds and installs, but crashes when trying to change 
settings/appearance.

- gnubg-0.9.0-1.tar.gz won't compile and make will quit with output:

#neuralnet.c: In function 'SSE_Supported':
#neuralnet.c:638: error: unknown register name '%edx' in 'asm'
#neuralnet.c:638: error: unknown register name '%ecx' in 'asm'
#neuralnet.c:638: error: unknown register name '%eax' in 'asm'
#make[2]: *** [neuralnet.lo] Error 1
#make[2]: Leaving directory `/usr/local/src/gnubg/lib'
#make[1]: *** [all-recursive] Error 1
#make[1]: Leaving directory `/usr/local/src/gnubg'
#make: *** [all] Error 2

- most important:
- gnubg-source-SNAPSHOT-20090119.tar (as well as *20090117.tar) do compile and 
install, but do only work without 3d-support (meaning gtkglext must be 
uninstalled while building snapshot and therefore there is no 3d; the possible 
2d gnubg runs very good (at least *20090117)).

When i try to build snapshot with 3d-support, it will compile and install, but 
won't run and quit upon start with message:

#set gui showids on
#(No game) (No game) gnubg: tnl/t_save_api.c:490: _save_upgrade_vertex: 
Assertion `oldsz == 0' failed.
#Aborted

If you have any ideas, in which way to approach this, i will be happy to try it 
out.
Note, these are two different problems; solving only one (eg. 0.90 or SNAPSHOT) 
is ok with me.
I can also provide you some config, system details if you think, they might be 
of help.
Is it possible, that i have missed some dependencies?
