Summary0001250: Crash on launch: invalid CPU subtype
Description
For some reason, the PowerPC side of the ardour universal binary is compiled with CPU subtype set to PPC7450. This incorrect compiiler setting prevents it from launching on my G3 hardware. Since AFAIK Ardour isn't G4-optimized (and certainly shouldn't crash on G3 CPUs), this is entirely the wrong CPU subtype.

If you merely want performance tuning for the 7450, please build this with "-mcpu=G3 -mtune=7450". If you are using auto-vectorization, please build a second time with "-mcpu=G3" and -no- mtune flag, then use lipo to glue the G3-compatible version to the G4/Intel binary. That way, the 7450 version will execute on G4 and G5 hardware, but will still be compatible with G3 systems.

thanks for the useful information. we'll fix up the build before the next DMG is released of ardour2 and 0.99.3/4

G3 is not supported at all anymore, so this becomes a moot issue
