Subject: [PATCH] Use LONG_BIT to define RADIX_BITS
|
|
This allows to avoid having to support each CPU architecture
|
individually.
|
|
Also, add the necessary defines in the makefile to expose
|
LONG_BIT. Adding those defines end up requiring using <sys/select.h>
|
as we're now using >= POSIX.1-2001 definitions of fd_set and friends.
