            Bug ID: 76789
          Assignee: dri-devel at lists.freedesktop.org
           Summary: [radeonsi] si_descriptors.c requires -std=gnu99 or
                    -fms-extensions
          Severity: normal
    Classification: Unclassified
                OS: OpenBSD
          Reporter: jsg at openbsd.org
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/Gallium/radeonsi
           Product: Mesa

Mesa is compiled with -std=c99 but this does not allow anonymous structs within
a union unless using a recent version of gcc.

When compiling with gcc 4.2.1 the following error is thrown when compiling the
gallium radeonsi driver unless configure.ac is changed to have either
-std=gnu99 or -std=c99 -fms-extensions.
