Well, it is supposed to work;-)

"pgxs" is just a reworking of the previous compilation infrastructure for
contribs so that it can be used outside of the main tree. So I don't feel
responsible for the actual dependency rules (say, whether all-lib make
sense), but I do feel responsible for the missing files, and the fixes
needed to adapt the infrastructure to the installation tree vs the source
tree.

Yep, I noticed.

Why can't you #include "port/win32/some_file.h" which would (I think)
avoid the issue without adding a win32 specific -I to all architectures??
I'm not sure I'm happy if I see a win32 path when compiling under some
unix.

Argh.

It looks like another missing file.

It could be also installed into lib/pgxs/src/backend so that the previous
definition works, but If it is possible to install it in lib (that is
maintainers agreee about it), then it looks better.

I'll try to submit a patch this week.
