            Bug ID: 31625
           Summary: glibc 2.39 fails to build on sh4-linux-gnu with 64bit
                    time_t, __sigtimedwait64' already defined
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: time
          Assignee: unassigned at sourceware dot org
          Reporter: doko at debian dot org
  Target Milestone: ---

I'm seeing this building a cross glibc 2.39 for sh4-linux-gnu using binutils
2.42 and GCC 13.2 branch.

The build fails with

--- Comment #2 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
I can not reproduce it with a bootstrap build with build-many-glibcs.py (which
does not use any non-standard glibc configure options), nor building glibc with
the generated compiler and enabling fortify. Is your gcc using non-default
compiler flags that might affect code generation?

Could you check the generated assembly file to see where the duplicate
__sigtimedwait64 comes from?

the build passes -D_TIME_BITS=64 -D_FILE_OFFSET_BITS=64

--- Comment #4 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
Right, these flags are not supported to be used to build glibc itself (similar
to BZ#31624).  Florian has added a suggestion on how to adjust the GCC config
flags to avoid passing on glibc.

*** This bug has been marked as a duplicate of bug 31624 ***
