             Bug #: 54292
           Summary: Errors due to conflicting strsignal headers
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: tobi@gcc.gnu.org
            Target: Darwin


This resembles PR31776.  My build from current HEAD fails with

I'm using an in-tree gmp, mpfr etc setup with contrib/download_prerequisites. 
I mention this because in gcc/config.log (attached) I see that the strsignal
configure tests apparently got confused by the location of gmp.h.
