Subject: SDL building "the unix way" on OS X
I just noticed that building current SDL CVS "the unix way" (using
configure/make) is (and has been for some time, it seems) broken.
That's because Sam updated to a newer libtool version, which removed my
"-framework" patches.
Attached is a patch which once again makes ltmain.sh aware of
"-framework". Note that this is simply a backport of the corresponding
changes in libtool CVS (i.e. the next libtool release will contain
those same changes).

13 This function uses the entire 8-bit [0\&.\&.255] range when converting color components from pixel formats with less than 8-bits per RGB component (e\&.g\&., a completely white pixel in 16-bit RGB565 format would return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8])\&. | |
14 .PP | |
15 If the surface has no alpha component, the alpha will be returned as 0xff (100% opaque)\&. | |
