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

* configure.in: Also pass -isystem option for GCC's include-fixed
|
||
|
|
directory.
|
||
|
|
* configure: Regenerate.
