I deliberately strip that out of CFLAGS when building asm files in Xen itself, as it makes gcc really unhappy (doesn't like #-prefixed end-of-line comments). Clearly it's not partial to $-prefixed macro names either, with older gcc versions. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
