This is a problem with arm header files in gcc, which defines a macro
named "Hint", and that's what causes this problem. Windows API pollutes
user namespace in a horrible way, and makes life a lot harder that it
needs to be. Here's a quick workaround: replace all instances of "Hint" 
in gcc/config/arm/arm.[ch] files with something else (eg Hint->ARM_HINT) 
and rebuild.

You can do it one of two ways:
 
1. build glibc with some dummy (such as empty) stdio.h and stdlib.h
   headers, install, and then use that to build gcc.
2. install the prebuilt runtime from a linux machine, and that's the
   method I've outlined in my howto. 

Method 1 can be easy or hard depending on how well you understand glibc
setup, which is non-trivial.
