            Bug ID: 108152
           Summary: gcc.dg/pr71558.c fails for LLP64
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: nightstrike at gmail dot com
  Target Milestone: ---

gcc.dg/pr71558.c has the following lines:

__SIZE_TYPE__ strlen (const char *);
void *malloc (__SIZE_TYPE__);
__SIZE_TYPE__ b =3D strlen (a);


These are good in that they support LLP64 through size_t, however they fail
because this test case is compiled with -ansi.  When using -ansi, the follo=
wing
warnings appear:

gcc.dg/pr71558.c:6:1: error: ISO C90 does not support 'long long' [-Wlong-l=
ong]
gcc.dg/pr71558.c:7:1: error: ISO C90 does not support 'long long' [-Wlong-l=
ong]
gcc.dg/pr71558.c:14:1: error: ISO C90 does not support 'long long'
[-Wlong-long]


And of course, on LLP64 systems, __SIZE_TYPE__ is in fact a long long.=20
Hopefully, -ansi can just be removed from the compile options, although I d=
on't
know how to do that.=
