             Bug #: 54447
           Summary: gmp in source does not work on alphaev68-dec-osf5.1a
    Classification: Unclassified
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: normal

         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: htl10@users.sourceforge.net


In the course of looking at bug 44959, I tried building gcc 4.6.1 with an
in-source sub-directory of gmp/mpfr/mpc, and encountered strange errors:

I tried working around the above errors as follows:

------------------------
the result still does not compare (bug likely due to other problems detailed in
44959). Anyhow, I suspect that the reasons for the above errors is that stage 1
uses system headers which do not have those C99(?) defines, but stage2 have
gcc's own patched headers, which have those defines, and therefore have those
config's during configure, but when it comes to actually compiling, still uses
the system headers, and therefore fails. These are my guesses.
