Glibc headers should be ANSI and Gcc compliant from the word go, and so
shouldn't *ever* need fixing.  The same goes for the Newlib headers; in
fact, if either of those sets of headers ever did need fixing, it should be
treated as a bug and the fix should be applied to the source in the Gnu /
Redhat CVS tree.

  It's almost the same as what I do for (non-linux) crosscompilers, with
one exception: I don't even bother deleting the sys-include, since include
and sys-include have the same contents, and since the $prefix/lib/gcc-lib/
$target/$version/include dir where the fixed headers live is first of all
on the path, it doesn't really matter to me that sys-include gets searched
before include, since I know for a fact that the version in sys-include
will be identical to the version in include.
