Tested on x86_64-pc-linux-gnu. OK for trunk?
---------- >8 ----------
This prevents the gcc driver erroneously accepting -nostdlib++ when it
should not when Ada was enabled.
Also, similarly, -nostdinc* (where * is nonempty) is unhandled by either
the Ada or D compiler, so the spec should not substitute those
either (thanks for pointing that out, Jakub).
Brought to my attention by Michał Górny <mgo...@gentoo.org>.
gcc/ada/ChangeLog:
* gcc-interface/lang-specs.h: Replace %{nostdinc*} %{nostdlib*}
with %{nostdinc} %{nostdlib}.
gcc/d/ChangeLog:
* lang-specs.h: Replace %{nostdinc*} with %{nostdinc}.
gcc/testsuite/ChangeLog:
* gcc.dg/driver-nostdlibstar.c: New test.
