[PATCH] Add libcc1 v1 compatibility to C compile feature

- Subject: [PATCH] Add libcc1 v1 compatibility to C compile feature
- Authentication-results: sourceware.org; auth=none
From: Alexandre Oliva <aoliva@redhat.com>
This patch adds v1 compatibiltiy to the C compile feature. The only change
in v1 concerns the handling of integer types, which permits GDB to specify the
built-in name for the type.
As far as I know, the C frontend is still on v0, so this patch is purely
precautionary. [By default C++ compile uses the equivalent of the C
frontend's int_type and float_type (aka the "v1" versions).]
gdb/ChangeLog:
* compile/compile-c-types.c (convert_int, convert_float):
Update for C FE v1.
