5b4de52083 BR 3392667: more reasonable limit for expression descent
Set an expression descent limit to 8192, which is more reasonable to
expect to work on most platforms. Furthermore, if getrlimit() exists,
then try to use it to see if we need to further limit the size.

97ea4adcf0 config/unconfig.h: eliminate #undef directives
config/config.h as generated by autoconf has #undef directives
commented out, but the autoheader-generated template contains them,
and config/unconfig.h should not contain them. Re-introduce
config/config.h.in, and postprocess it to generate config/unconfig.h
by commenting out all the #undef directives, just as configure does.

8b6e6bf04f config.h: separate function and function pointer attributes; automate
Separate out function and function pointer attributes, as not all
versions of all compilers support both.

Have macros related to function attributes auto-generated by
autoheader. As a result, rename config.h.in to unconfig.h, to make it
more obvious that it is really intended to be included from some C
programs.

0bddd0f1b1 autoconf: move aux directory, define AC_CONFIG_AUX_DIR()
The name "aux" is reserved on Windows platforms, a legacy from CP/M
via MS-DOS. Rename it to "helpers".

Turns out that that directory wasn't actually used properly, because
AC_CONFIG_AUX_DIR was never defined, and there was a redundant copy of
install-sh checked into the base of the source tree.

Try to make nasm_assert() do a static assert if the argument can be

64b56eaa39 configure: add -Wno-shift-negative-value
Shifting negative values is undefined in standard C, but we have tons
of dependencies that signed arithmetic is 2's-complement in the code
anyway, and on gcc-like compilers we pass the -fwrapv option to
indicate exactly that. Therefore, this is not a valid warning in our
case and should be suppressed.
