Update gcc6809 patch to work with pragma=newsource An updated version of the gcc6809 patch is provided. This update removes some incompatible syntax left over from the original gcc6809 patch that used as6809. It was doing something that doesn't work with lwtools anyway. Namely, trying to use the assembler to set the layout used by the linker. Now thats all back to front when you think about it. With this update, it is now possible to use the "as" wrapper with --pragma=newsource enabled and be able to pass assembly code through the C preprocessor without worrying about extraneous spaces causing problems.

114 This is identical to the -2 version except it fixes the crt0.S file so it
115 builds properly with the --pragma=newsource option. In fact, it never did
116 build properly due to spaces in operands anyway. However, since gcc6809
117 doesn't come with a C library, it hasn't proved to be an issue.

122 It's also worth noting that there are features inherited from previous
123 versions of gcc6809 that are not properly supported by these patches. In
124 particular, banking and "far calls" are not supported because there are no
125 targets supported by lwtools that do anything meaningful in the face of such
126 things. Patches to clean that up are also welcome. Either to do something
127 meaningful or to remove such features entirely.
