Remove the Mark() and Release() procedures from the Pascal compiler and
...
standard library, because they never worked and come from an achingly old
version of the Pascal specification. Fix the implementations of New() and
Dispose() to use the standard C memory allocator rather than rolling their own
(also in C). Write test!

Change sbrk() to take an int rather than an intptr_t (following the OpenBSD way
...
rather than the Linux way; various non-C bits of the ACK assume it takes an
int, so it's cleaner).

Combine brk() with sbrk(); modify brk() to update the sbrk(0) value.

Made csa and csb work with mcg; adjust the libem functions and the

corresponding invocation in the ncg table so the same helpers can be used for
both mcg and ncg. Add a new IR opcode, FARJUMP, which jumps to a helper

A bb's regsin are no longer the same as those of its first instruction;

occasionally the first hop of a block would try to rearrange its registers (due
