[hoc-cvs] hoc/HOC_cbits MsgSend.h,NONE,1.1

[Wolfgang T. <wth...@us...>]

Update of /cvsroot/hoc/hoc/HOC_cbits
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv7280/HOC_cbits

Added Files:
	MsgSend.h 
Log Message:
Make HOC.MsgSend compile via C to work around a bug in GHC 6.2's NCG for
PowerPC. The NCG doesn't generate the proper dynamic linker stubs for
taking the address of dylib-imported functions. The bug will be fixed in
GHC 6.4, so we will be able to remove the -fvia-C flag again then.

Compiling via C required adding a new .h file with the prototypes for
objc_msgSend and friends; Apple is not helping us here by letting a single
line of Objective-C slip into an otherwise plain C header file.

Also, removed the previous workaround from HOC/HOC-macos.conf.
