o - merge:
copy and strip
ar and ranlib
nm, size, and objdump
o - make the long options more consistent.
o - make ATT and BSD versions -- perhaps the options should be
controlled by an environment variable.
o - Calling +help or +version should exit with a successful status (ie 0)

/*
alloca -- (mostly) portable public-domain implementation -- D A Gwyn
last edit: 86/05/30 rms
include config.h, since on VMS it renames some symbols.
Use xmalloc instead of malloc.
This implementation of the PWB library alloca() function,
which is used to allocate space off the run-time stack so
that it is automatically reclaimed upon procedure exit,
was inspired by discussions with J. Q. Johnson of Cornell.
It should work under any C implementation that uses an
actual procedure stack (as opposed to a linked list of
frames). There are some preprocessor constants that can
be defined when compiling for your specific system, for
improved efficiency; however, the defaults should be okay.
The general concept of this implementation is to keep
track of all alloca()-allocated blocks, and reclaim any
that are found to be deeper in the stack than the current
invocation. This heuristic does not reclaim storage as
soon as it becomes invalid, but it will do so eventually.
As a special case, alloca(0) reclaims storage without
allocating any. It is a good idea to use alloca(0) in
your main control loop, etc. to force garbage collection.
