Date: Thu, 13 Sep 2001 14:14:42 -0400 From: "David Chait" <> Subject: -- Message: 502 -- Next: 503 N -------------------------------------------- now bracketed with (MWERKS && macintosh), so it'll work under metrowerks under any kind of mac build. Project Builder probably uses pack properly as it is GCC under the covers, so not worrying about it... :) it sets packing to 68K 4-byte alignment, and turns on enumsalwaysint. resets them both to project defaults when done. note that if a project sets these things in a header and expects the settings to last throughout a C file (which is a nasty thing to do), it won't work. I think there's an overall-state push/pop system, but it's a deprecated interface so I'm loathe to use it...
