syscalls, unless WITHOUT_SYSCALL_COMPAT is defined. The default case will have the .c wrappers still. If you define WITHOUT_SYSCALL_COMPAT, the .c wrappers will go away and libc will make direct syscalls. After 7-stable starts, the direct syscall method will be default. Approved by: re (kensmith)

particular: SYSCALL() makes a syscall, with errno handling, and continues execution directly after the macro in the non-error case. RSYSCALL() is just like SYSCALL(), but returns after success. Both SYSCALL(name) and RSYSCALL(name) export "__sys_name" as a strong symbol, with "_name" and "name" as weak aliases. PSEUDO() is just like RSYSCALL(), but skipping the "name" weak alias. It still does "__sys_name" and "_name". Change i386 to add errno handling to PSEUDO. The same for amd64 and sparc64, with appear to have copied the behavior. ia64 was correct (as was alpha). Just remove some apparently unused variants of the macros. (untested!) I believe powerpc is correct. Fix arm to not export "name" from the PSEUDO case. Remove apparently extra unused variants. (untested!) The errno problem manifested on i386/amd64/sparc64 by having "PSEUDO" classified syscalls return without setting errno. eg: "addr = mmap()" could return with "addr" = 22 instead of setting errno to 22 and returning -1.

net: endhostdnsent is named _endhostdnsent and is private to netdb family of functions. posix1e: acl_size.c has been never compiled in, so there's no "acl_size". rpc: "getnetid" is a static function. stdtime: "gtime" is #ifdef'ed out in the source. some symbols are specific only to some architectures, e.g., ___tls_get_addr is only defined on i386. __htonl, __htons, __ntohl and __ntohs are no longer functions, they are now (internal) defines in .
