hi folks,
this is an updated set of descriptions for netbsd/sparc & netbsd/sparc64.
changes from the previous version mostly are to fully use the new gcc
#include style (ie, list them all in config.gcc).
i've tested the 32-bit version several times over the past few months
and it's worked pretty well each time. 64-bit continues to be a problem..
could someone commit these ? thanks,
.mrg.
