The change below switches to the _MIPS_SZLONG macro so that compilation with e.g. GCC 4.1.2 succeeds. This is a user API header so I think this is even more important, for older userland support. The change adds an unsuccessful default too, to catch any compiler configuration oddities. Signed-off-by: Maciej W.
