History
Noam Postavsky 13c6f1d185 Use expanded stack during regex matches 
While the stack is increased in main(), to allow the regex stack
allocation to use alloca we also need to modify regex.c to actually take
advantage of the increased stack, and not limit stack allocations to
SAFE_ALLOCA bytes.

* src/regex.c (MATCH_MAY_ALLOCATE): Remove obsolete comment about
allocations in signal handlers which no longer happens and correct
description about when and why MATCH_MAY_ALLOCATE should be defined.
(emacs_re_safe_alloca): New variable.
(REGEX_USE_SAFE_ALLOCA): Use it as the limit of stack allocation instead
of MAX_ALLOCA.
(emacs_re_max_failures): Rename from `re_max_failures' to avoid
confusion with glibc's `re_max_failures'.
* src/emacs.c (main): Increase the amount of fixed 'extra' bytes we add
to the stack.  Instead of changing emacs_re_max_failures based on the
new stack size, just change emacs_re_safe_alloca; emacs_re_max_failures
remains constant regardless, since if we run out stack space SAFE_ALLOCA
will fall back to heap allocation.

This directory contains the source files for the C component of GNU Emacs.
Nothing in this directory is needed for using Emacs once it is built
and installed, if the dumped Emacs is copied elsewhere.

See the files ../README and then ../INSTALL for installation instructions.

The file 'Makefile.in' is used as a template by the script
'../configure' to produce 'Makefile'.  This is the file which actually
controls the compilation of Emacs C source files.  All of this should
work transparently; you should only need to change to the parent
directory, run './configure', and then run 'make'.
