My experience is that this works well on Linux, but is actually slower on
PowerPC Mac OS X...not sure if that's an architecture issue or a scheduler
issue, though, and haven't tried it on Intel Mac OS X.
- A change to define CXX in fatbuild, which comforts the configure script a little, even if we don't use C++ anywhere.
- Some code to see how many CPU cores exist and parallelize make across them.
- CFLAGS that apply to both archs are specified seperately (-O3, -pipe, etc)
- -fvisibility=hidden for the gcc4 builds
- a "clean", "clean-ppc" and "clean-x86" command
- Fix to SDL_config_macosx.h for the HAVE_ALLOCA_H thing.
Now builds on an Intel Mac.
The attached patch changes configure.in to use "-framework FOO" instead of
"-Wl,-framework,FOO".
This avoid some issues with certain versions of libtool that do not handle
-framework properly.
Some versions of libtool will try to reorder the two parts of the option, or
render the 2nd part of the argument to the relative path of a non-existent
library.
Note: It is not enough if SDL uses a version of libtool that does this
correctly, because these -framework options show up in "sdl-config --libs".
Hence, some 3rd party apps which still ship with an old libtool have troubles
compiling under Mac OS X.

Subject: Re: Updating SDL for RISC OS
I've attached a zip file with three diffs to get SDL to build on RISC OS.
configure.in.diff and makedeps.sh.diff have been modified so that they
can build the assembler file in video/riscos. You may want to double
check these as I don't know a lot about unix shell programming.
(I've tested them cross-compiling on cygwin).
sdlsysthread.diff is the changes required to SDL_systhread.c for RISC
OS. As you suspected with these changes in place you can delete the
RISC OS specific threading code in thread/riscos.
I've also renamed SDL_riscosASM.s to SDL_riscosASM.S, but I'm never
quite sure how to rename files in CVS, so if you could to this it would
be appreciated.
