Summary: distutils adds (unwanted) -xcode=pic32 in the compile comman

Initial Comment:
After configuring, making and make installing the
svn-trunk version with sunstudio11 on a Solaris 9 box,
an extra '-xcode=pic32' argument is added to the
compile-command when I try to install numarray using
the setup.py that comes with numarray.

To configure python I first executed:

export CC=cc
export CFLAGS="-xarch=v9" # to force 64bit compilation
export EXTRA_CFLAGS="-xarch=v9" # 
export CXX=CC
export CXXFLAGS="-xarch=v9"
export F77=f77
export FFLAGS="-xarch=v9"
export LDFLAGS="-xarch=v9"

Note that EXTRA_CFLAGS needs to be defined too,
otherwise python itself will not be compiled with the
-xarch=v9 option.

Afterwards I want to install numarray using the
setup.py (`python setup.py install` command). During
compilation of numarray I can however see that
distutils is adding -xcode=pic32 on the command-line.
Afterwards distutils is not able to link because there
now is a mix of 32bit and 64bit code.

You must be misunderstanding something. -xcode=pic32 does
*not* mean that the code ought to be compiled for the 32-bit
processor mode. Instead, it means that the PIC (position
independent code) offsets are encoded using 32-bit numbers,
which works for both 32-bit and 64-bit code as long as the
size of the code does not exceed 4GiB.
