That's the least I can do ;-)

Well, you never know...
Is there a way to check this?

To be sure I started again (removing all dirs
and without any environment variables, which would
point to my install of "old scipy", including the gcc 3.4.4).
This means that now I am running with
gcc -v
Using built-in specs.
Target: x86_64-suse-linux
Configured with: ../configure --enable-threads=posix --prefix=/usr
--with-local-prefix=/usr/local --infodir=/usr/share/info
--mandir=/usr/share/man --libdir=/usr/lib64 --libexecdir=/usr/lib64
--enable-languages=c,c++,objc,f95,java,ada --enable-checking

--enable-shared --enable-__cxa_atexit --without-system-libunwind
--host=x86_64-suse-linux
Thread model: posix
gcc version 4.0.2 20050826 (prerelease) (SUSE Linux)

 ./newcore/scipy/base/src/ does not contain this file,
but
 ./newcore/build/src/scipy/base/__ufunc_api.h
does
[ I send you the file off-list ]

OK, just let me know if you need any further information
or test runs etc.
