Hi Kazu,
I swear that last week I couldn't build past:
verify_addr = (local - bt->stackbuf) + bt->stackbase;
without a gcc error on the two char * in the parentheses being
used in a ulong assignment. Last week it required casts on both
char * to build for me. This week build of the same workspace
of expanded source works through the same line without any casts.
Below is a patch to replace the one in this thread's header post.
It is cleaned of the casts I previously had in the line above.
It builds fixes the problems I described in this thread's header
and is unmodified other than removal of the casts I previously
had in the line above.
I'm sorry for the trouble getting it tidy.
