This needs the 4 compat-poll patches posted earlier.
Needs a different link order in Makefile: libintl before libiconv.
This may affect other platforms, so needs some checking.
Also I'm not really sure how to best #ifdef the #include <strings.h> 
and the typedef (u)intptr_t. 
Furthermore the -DHAVE_STRING_H=1, needed for
compat/fnmatch/fnmatch.c doesn't look quite right to me?
