Re: [MiNT] MiNTLib for ColdFire
I made some investigation, it appears that ColdFire support can be added in
the MiNTLib with a reasonable amount of work.
- 3 C headers require minor changes in inline assembly
- there are 16 assembler sources, they all require some minor patching.
The attached patch adds support in the Makefiles for building the ColdFire
variant called "libv4e". That build is disabled by default, so it will not
break anything.
I will provide further patches for the sources.
If you feel that we should continue that way, please commit this patch.

+ Added build support for ColdFire V4e libraries.
+ The new variant is called libv4e, and is built with the -mcfv4e option.
+ Since that option is only available in GCC 4.x and the sources are not
+ yet compilable for ColdFire, the build of that library is currently
+ disabled by default.
