The NetBSD libc provides a mechanism to have versions of system calls. By 'renaming' symbols to a new version, freshly compiled programs will automatically use the new symbol iff they use the proper header files. The old, not renamed, version of the symbol will still exist (after being moved to the compat directory), so old programs can still link. Since MINIX doesn't support dynamic linking, the whole rename mechanism doesn't really work for us. However, removing it would create a huge diff with the current NetBSD libc. A lot of the compat code relies on things we don't (seem to) have, and therefore does not get built and linked. This causes trouble for tools like autoconf, which will fail to find the renamed symbols. For example, currently select gets renamed to __select50 in libc. Autoconf looks for 'select' and doesn't find it and reports we don't have it. This is where the compat.S stub comes into play: it generates the old symbols and jumps to the new symbols. However, as this is done in one object file, all renamed symbols get linked together, causing binaries to be huge. This patch fixes that by generating an object file for each renamed symbol. This patch also makes the MISSING_SYSCALLS more complete and marginally reduces the diff with NetBSD.
