Summary: configure uses GCC's keyword typeof
           Product: Wine
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: build-env
        AssignedTo: [e-mail]

configure script uses typeof() which is a GCC extension not available in C99.

Running configure script with a C99 compliant compiler (eg gcc --std=c99)
reports errors about missing libs/features.
