builtins. Required changes:
- be careful about creeping in deallocate: it may be followed by
something that is not a cut nor a proceed.
- include new instruction in absmi.c: it is a merge of execute and
call_cpred.
- change compiler to generate execute even for C builtins.
- be careful with dexecute: it may not be done if execute_op is a C
builtin.
- if we are in execute_cpred, the garbage collector cannot trust P:
instead it must look at CP to find out the size of the current
environment. The macro gc_P receives that information.
- We don't need to change CP if we do a meta-call from within
execute_cpred (and we in fact cannot). Check places where we do
meta-calls: exec, clause in cdmgr, and lu_recorded.
process overflows as high-level as possible;
introduce overflow related errors
ExpandWorkSpace should never call Error: use ErrorMessage instead,
format_putc should never release memory, causes memory corruption,
Linux does not like MAP_FIXED, it can overwrite the actual program
code.
condor: twick configure to disable readline with condor.
