5726c2e490 Prevent stack overflow in sexp_mark_one (issue #601) 
Replace explicit recursion by heap allocations
in sexp_mark_one code.
This prevents crashes caused by stack overflow.
In particular, fixes issue #601.

As an optimization, allocate a fixed sized stack buffer first,
which should be enough for "normal" uses.
When that stack overflows, switch to heap.

Also, store "ranges" on the stack, instead of the actual sexp's,
using the fact that sexp's of a single parent are continous in memory.

This patch doesn't remove recursion on the context saves
because it didn't seem like they overflow in practice.
But changing that is simple having the stack interface.

f449bd157d fix compilation under std=c89 
There were few things that prevented successful compilation
using c89 standard. (and other c* standards in case of gcc).
Fix them in this small patch.

Changes in 27/rand.c:
- Use __GNU_SOURCE__ instead of __GNU_LIBRARY__
  or else any of -std=c* options don't work with gcc
- Add a check before using rand_r() as suggested in rand_r(3)
- Move _WIN_32 definitions to "else" branch because it uses the most portable version

521e23e3c7 Reduce error in sexp_read_float_tail (from Taylor R Campbell) 
scale*10 is computed exactly until scale exceeds 2^54/10; in
contrast, scale*0.1 may not be computed exactly, and fl(0.1) is not
even 0.1.

WARNING: This change is not complete -- it does nothing to prevent
overflow with very long strings of digits after the decimal point.

e092923aac Win32: Fix win32 port 
Try to fix win32 port. Now it runs both on Win32/Win64.

Win64 port currently depends on 128bits arithmetic thus it does not run on
MSVC.

Makefile now have EXCLUDE_POSIX_LIBS knob to exclude posix related library
from build.

Introduce msys PLATFORM for Makefile.detect to use MSYS's POSIX
emulation layer. It is intended for linking against MSYS tools; it is
not for embedding to Win32 applications.
