There are two problems:

1. POSIX feature flags get set *after* the first #include of
a POSIX header. This likely will confuse the POSIX feature flag
system. This probably also explains why the code later #defines
flags internally used by that system.

2. The feature flag system special-cases gcc. This makes
things rather ugly for us because the type returned by
readdir() changes with the compiler: dirent * for gcc,
dirent64 * for icc. Those types, however, have the same
layout if 64 bit support was enabled by #defining
_FILE_OFFSET_BITS to 64 before #including a POSIX header.
