Yeah - and it makes it pretty confusing to find the functions then. > Or we could move the implementation into a header file, with an extra __ > prefix, and have the C stubs call those inlines, so we have exactly on > instantiation. Your real mode code can then call the inlines. I like this version. That way everyone should be happy :) Alex _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
