Successful 32-bit built on OSX with only sed, fftw, and gfortran added to vanilla Snow Leopard

[Richard Campbell]

The README.MacOS file needs to be updated to reflect this MUCH smaller list of 
critical dependencies (I don't think fftw is even needed, but Octave wouldn't 
be very useful to me without it.)

- gfortran from r.research.att.com/tools
- gnu sed compiled and installed with --prefix=/usr
- fftw3 and fftw3f built as universal binaries (CFLAGS, FFLAGS, LDFLAGS all set 
to "-arch i686 -arch x86_64", configure with --disable-dependency-tracking)

- octave 3.3.54:
export CFLAGS="-m32"
export FFLAGS="-m32 -ff2c"
export CPPFLAGS="-m32 -D_REENTRANT"
export LDFLAGS="-m32"

./configure --disable-readline --disable-docs
make
./run-octave

I still get a cs-list error when I try to print:

octave:3> print('-dpng','test.png')
warning: print.m: ghostscript not found in EXEC_PATH.
warning: print.m: Ghostscript binary is not available.
warning: print.m: epstool binary is not available.
warning: print.m: fig2dev binary is not available.
warning: print.m: pstoedit binary is not available.
error: invalid assignment to cs-list outside multiple assignment.
error: matrix cannot be indexed with {
error: evaluating argument list element number 3
error: called from:
error:   /Users/xnk/Downloads/octave-3.3.54/scripts/plot/print.m at line 377, 
column 9

I will attempt the 64-bit version with the wrapper described elsewhere, but 
once this cs-list problem is addressed I think this is ready to go in 
README.MacOS for 32-bit at least.
