Without this chibi can crash after 129 open file descriptors.
Note the bug referenced would also indirectly be fixed if
process->string-list properly closed its ports, but we
shouldn't rely on that.

Prevent crashing from arithmetic exception when spawning lots of commands
...
This fix is rather dumb, but it prevents things from crashing when
forking a lot and creating file handles. I assume that this is where
the filehandles go, but I don't have a good guess.

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.

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

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.
