           Summary: xxx.c:1:20: stdint.h: No such file or directory
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: preprocessor
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: danglin at gcc dot gnu dot org

0

stdint.h doesn't exist on hppa2.0-hp-hpux11.00.  The message is correct
but the exit value for gcc is wrong.  Adding "-Werror" doesn't affect the
exit value.

This causes configure checks in libiberty and libstdc++-v3 to break.  For
example,

configure:5490: checking for stdint.h
configure:5507: /xxx/gnu/gcc-3.3/objdir/gcc/xgcc -B/xxx/gnu/gcc-3.3/objdir/gcc/ 
-B/opt/gnu/hppa2.0w-hp-hpux11.00/bin/ -B/opt/gnu/hppa2.0w-hp-hpux11.00/lib/ -isy
stem /opt/gnu/hppa2.0w-hp-hpux11.00/include -isystem /opt/gnu/hppa2.0w-hp-hpux11
.00/sys-include -c -O2 -g -O2 -O2 -g -O2 conftest.c >&5
configure:5551:20: stdint.h: No such file or directory
configure:5510: $? = 0
configure:5513: test -s conftest.o
configure:5516: $? = 0
configure:5527: result: yes

The result is numerous regression in the g++ testsuite because stdint.h
gets included by the v3 headers.
