            Bug ID: 106036
           Summary: Missing stdint.h include in libgcc/libgcov.h
           Product: gcc
           Version: 12.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: gcov-profile
          Assignee: unassigned at gcc dot gnu.org
          Reporter: kacper.slominski72 at gmail dot com
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

The libgcc/libgcov.h header (and users of it) do not include stdint.h before
using int64_t and uint64_t (via typedefs in gcc/gcov-io.h).

Looking a bit deeper, gcc/tsystem.h includes a bunch of libc headers but omits
stdint.h, which, on glibc, gets inadvertently brought in by stdlib.h and
sys/types.h, but POSIX does not specify that it needs to.
