1 GCC trunk now has multiple internal headers directories, one
2 containing the self-contained GCC-provided headers and one containing
3 the <limits.h> (not self-contained but including libc's <limits.h> or
4 a fixed version thereof) and the fixed headers; more such directories
5 may be added in future.
7 When glibc uses -nostdinc, it needs to use -isystem options for all
8 these internal directories. This patch teaches it about the
9 include-fixed directory (and is harmless with old GCC versions without
