parent | Cleanup the FREEBSD_NATIVE stuff, which we don't use anymore in this context. (diff) |
Define "OBSTACK_CHUNK_SIZE" as getpagesize().
Our malloc can allocte pagesized blocks efficiently and the EGCS default
size of 4072 bytes is not optimal.
Protect #define's and other minor syncing with
src/contrib/egcs/gcc/config/freebsd.h
