 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:
-  * C99 integer types 'inttypes.h' 
   * sys/statvfs.h to convert from BSD/old-glibc statfs to SUS statvfs
   * rfc2553 hostname resolution (methods/rfc*), shims to normal gethostbyname.
