+That said, there are lots of finicky problems that must be dealt with even
 between the supported OS's. Primarily the path I choose to take is to put
 a shim header file in build/include that transparently adds the required 
 functionality. Patches to make autoconf detect these cases and generate the 
 required shims are OK.
 
 Current shims:
-  * C9x integer types 'inttypes.h'
