gnustep-base-1.5.2 on darwin

[Carl Eugen Hoyos]

I installed gnustep-*-1.5.2 on a powerpc-darwin, and here are the changes
I had to make:

In target.make, I had to add
-read_only_relocs warning
to the shared_lib_link_cmd for gnu-compiler. I don't think two darwin
sections in target.make and HOW_TO are necessary, both darwin5 and
darwin6 should have identical instructions (to the user and the Computer ;-)
The recommended compiler should be gcc-3.2.2, because gcc-3.2.1 did not
build out of the box.
It should be mentioned in the HOW_TO that you need to
configure --with-library-combo=gnu-gnu-gnu
if you want the whole library on darwin.

I had to change a variable definition in NSInvocation.h to work with
GSFFICallInvocation.m, but I guess that's already changed in cvs.

I couldn't compile gnustep-guile, so no gnustep-tests on darwin!

In the Testing subdirectory, the following programs produce problems:
nsarray crashes immediately
nsbundle doesn't load the bundle

nsinvocation crashes with this output:

nsconnection_client crashes while nsconnection_server works perfectly and
receives/sends structs to ix86-linux and sparc-solaris2.7:
...
String:

Thanks for everybodys work!
