[pypy-issue] [issue1635] numpy: compilation failed, unresolved external (msvc)

[mattip]

mattip <matti.picus at gmail.com> added the comment:

link is missing python27.lib, which is located in <pypy_base>\include. This is 
an import lib (telling the linker that the functions in it are located in 
libpypy-c.dll), used in MSVC instead of linking directly to a *.dll or *.so like 
gcc does.

CPython solves this with a trick - in <cpython_base>\include\pyconfig.h there is 
a pragma that magically adds the import lib to anything that #includes 
pyconfig.h I tried doing this in our pyconfig.h which seems to fix the problem 
for me.

Could you try replacing pypy's pyconfig.h with the one attached and update the 
issue accordingly?
