Standard macro sets are looked up based on parser and preprocessor keyword from individual modules. The "standard" NASM parser macros now reside in the NASM parser, so when the GAS parser is used with the NASM preprocessor, the NASM-specific macros are no longer defined. Object-format specific macros are now individually defined by each object formatm module. This allows for the object formats to be independent of the NASM preprocessor module and yields a small optimization benefit as unused object format macros don't need to be skipped over. Also add GAS macro equivalents for the Win64 SEH more complex directives [1]. [1] Requested by Brian Gladman <brg@gladman.plus.com> svn path=/trunk/yasm/; revision=2082
