sac-from-c and quicksort will not compile, for several reasons

[bernecky]

I just did a git clone(git submodule init; update...); cmake; make on this, and ran into several faults with
sac-from-c and quicksort during the make, shown here:

I have a fix for the sac_from_c linker problem. The fault has to do with different ways that various ld (*nix linker)
tools treat -L and -l libraries, as briefly discussed here:
https://stackoverflow.com/questions/7826448/linking-libraries-with-gcc-order-of-arguments
I'll commit this fix shortly.

Committed sac_from_c fix earlier today. The IntStack stuff is pointing to
line 983 of:

/usr/local/include/sac2c/1.3.3-MijasCosta-581-g8d98d/debug/runtime/essentials_h/std.h

If the comments are to be believed:

This mirrors __DEFAULT for now (step-by-step introduction of bitarrays)

I'll leave that for the author of that code to repair.
