dlltool.c(244) defines PAGE_SIZE

The PAGE_SIZE symbol is/should be defined in limits.h on a POSIX system (see
http://www.opengroup.org). NT POSIX subsystem (SUA) defines it to 0x10000
(10*0x1000). In my headers PAGE_SIZE is defined as an enum and dlltool.c
generates a compiler error due to PAGE_SIZE is defined before including system
headers.

I need advise how to fix this. 
Assuming setting PAGE_SIZE to 0x1000 is preferable, we can let dlltool.c set an
explicit value after including the system headers, like this:
