Whatever the other issues about including these headers at all, any system
header (C or C++) must always be included *after* config.h, as config.h
may define feature test macros that are only properly effective if defined
before any system headers are included, and these macros (affecting such
things as the size of off_t) need to be consistent throughout GCC.
