I now have the use of --dump-pch and --load-pch working for script-based invocations of pbxbuild when optimizations are turned off. Not quite what I had in mind but it'll do. This works fine for debug builds with optimization disabled.

When I do a release build I run into all kinds of grief, the first being gcc is upset that the use of a precompiled header is somehow inconsistent with the use of the compiler flag -mdynamic-no-pic, which appears to be Apple-Only, PowerPC specific.

The use of that flag appears to be a consequence of using pbxbuild and setting optimizations to level 2. It doesn't seem to appear to matter if I build the precompiled header with or without -mdynamic-no-pic present, gcc doesn't like it. Is there a known way to address this when using precompiled headers?
