           Summary: Bootstrap failure: libiberty/regex.c: error: two or
                    more data types in declaration specifiers
           Product: gcc
           Version: 4.5.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: skunk@iskunk.org
              Host: powerpc-ibm-aix4.3.2.0
            Target: powerpc-ibm-aix4.3.2.0
             Build: powerpc-ibm-aix4.3.2.0


Bootstrapping on this AIX system bombs out with

The cited portion of include-fixed/sys/types.h looks like this:

--------8<--------
typedef uint_t          uid_t;          /* user ID */
typedef uint_t          gid_t;          /* group ID */
typedef __ptr32         mid_t;          /* module ID    */
typedef int32long64_t   pid_t;          /* process ID */ <--- LINE 212
typedef int32long64_t   tid_t;          /* thread ID */
typedef char            slab_t[12];     /* security label */
typedef long            mtyp_t;         /* ipc message type */
-------->8--------

If I change up the compiler invocation from -c to -E, that same portion looks
like this:

--------8<--------
typedef uint_t uid_t;
typedef uint_t gid_t;
typedef __ptr32 mid_t;
typedef int32long64_t int;   <--- HMMM
typedef int32long64_t tid_t;
typedef char slab_t[12];
typedef long mtyp_t;
-------->8--------

Interestingly enough...

> grep pid_t /tmp/gcc-4.5.2-build/libiberty/config.h
#define pid_t int

If I stick in an "#undef pid_t" right before the offending line, regex.c
compiles successfully.
