See if we can generate a GNU makefile directly from the Xcode project file
Include header files directory
Exclude pch files from headers
Be sure to quote header file paths in case they have spaces in them
Include full path to .m files
Include 'src' in path to .m files
Include generated "Headers" in include path
Also copy .m files

Apparently the build gets confused when header files exist next to .m files. Making copies prevents this
Ignore directories created during build
Merge branch 'gnustep' of github.com:Pixate/pixate-expression-machine into gnustep
Remove PXInstructionCounter from iOS build for now
Special case .lm files
Be sure to include building of the generate .yy.m file
Make changes to allow EM to run under GNUstep

Most of the changes related to removal of dispatch_once. Some changes will need to be reworked, specifically in PXInstructionProcessor, and PXObjectValue
Merge branch 'master' into gnustep

Conflicts:
