Re: [Patched] What to add to GNUmakefile to compile with a .pch file that came from Xcode project?

[Nicola Pero]

Thanks Chris

excellent contribution - we definitely want to support the .pch  
extension for precompiled headers! :-)

I have applied to trunk a slight different patch (in attach for your  
interest) which is simpler and supports any possible
extension for precompiled headers.  In practice, I simply removed the  
hardcoded '.h' from the variables and rules. :-)

I briefly tested it with precompiled headers on Apple both with a .h  
and .pch extension, and it works for me.  Can you confirm
that it works for you as well ?  (you can try it out from subversion  
trunk ... will soon be released as part of gnustep-make 2.4.0)

Thanks
