I am having several issues with this patch:
a) Has this code been tested with/checked against sparc64-rtems4.11
toolchains?
I haven't tried to check which code paths are being used with the
sparc64 and hardly won't have a possibility to check in near future, so
this question could be a red herring.
b) This code should use __sparc__ instead of __sparc.
__sparc is a pre-POSIX anachronism, is still supported by GCC but
actually should not be used anymore.
