Looks good. I think the Compaq Visual Fortran Compiler (the compiler was
bought from Compaq by Intel) code has the same error. Maybe you want to fix
that.

Patch worked. Next issue here:

http://projects.scipy.org/scipy/scipy/ticket/242

MSVC doesn't like cephes redefining fabs, which the compiler considers to be
an instrinsic function.

Next issue after this: building with the following site.cfg fails on
Windows.

[blas_src]
src_dirs = C:\home\albert\work2\blas
[lapack_src]
src_dirs = C:\home\albert\work2\lapack

The reason this fails is that the step where the LAPACK files are linked
into a static library generates command line arguments that are about 80000
characters long. The limit seems to be 32k:

The way to get around this is to use the Windows @ trick. You put the
command line arguments in a temporary file (the tempfile module is probably
your friend here) and execute the command as:

lib.exe @tempfilecontainingcommandlinearguments

This is what SCons does when linking large numbers of files on Windows.
