[patch] "single step" atomic instruction sequences as a whole.

[Luis Machado]

Daniel,

Thanks for your reply. The syntax problem was corrected.

I've ran the gdb_mbuild.sh script and had no problems that are directly
related to my patch. I had a compilation problem with the spu-elf, but
that seems to be in cvs-HEAD as well. I also changed the return type of
the software single step method for spu-elf and the local return values
from the method ("return" to "return 1"), since they were still void.

The wince.c file modification was droped due to its removal from the
tree.

Attached follows the patch that only changes the infrun bits and also
the return type of the software_single_step methods for various archs.

Thanks for the hint on this.

Regards,
