GCC trunk now has multiple internal headers directories, one |
| yann@1004 | 2 |
containing the self-contained GCC-provided headers and one containing |
| yann@1004 | 3 |
the <limits.h> (not self-contained but including libc's <limits.h> or |
| yann@1004 | 4 |
a fixed version thereof) and the fixed headers; more such directories |
| yann@1004 | 5 |
may be added in future. |

When glibc uses -nostdinc, it needs to use -isystem options for all |
| yann@1004 | 8 |
these internal directories. This patch teaches it about the |
| yann@1004 | 9 |
include-fixed directory (and is harmless with old GCC versions without |
| yann@1004 | 10 |
that directory). |

* configure.in: Also pass -isystem option for GCC's include-fixed |
| yann@1004 | 15 |
directory. |
| yann@1004 | 16 |
* configure: Regenerate. |
