FSEvents uses AC_CHECK_DECLS in its configure script.  AC_CHECK_DECLS
has an internal test where it tries to figure out what flag to pass
to the compiler to make compilation of a certain piece of code _fail_.
But nobinary_dummy "succeeds" at compiling anything, which makes it
impossible for this configure test to succeed.  Work around the issue
by pre-seeding the cache with the desired outcome for the internal test.

Also, fix the incorrect test guarding the assignment of CC to
$BINDIR/nobinary_dummy.

Future versions of Pike may be used to run the precompiler. They may be
incompatible with the version that precompile.pike was written for when
npt running in the correct compat mode.

Fixes issues like eg the Pike 8.0 precompiler being incompatible
with the Pike 9.0 type checker.

The BSD libc used in Darwin rejects any negative tm_year outright.

Fixes calculation for dates past 2038-01-19T03:14:07 UTC.

The issue was caused by the C division operator rounding negative
values toward zero rather than toward negative infinity. Now the
dividend should stay positive to avoid surprises.

Note that mktime() is best-effort for timezone offsets other than 0.

Note that mktime() is best-effort for timezone offsets other than 0.

Note that localtime() is best-effort, and likely has issues on
times near midnight December 31 some years.

Also makes some testsuite adjustments.

mktime() on Haiku appears to attempt to support time before
1970-01-01T00:00:00 albeit it is off by one second. Add a
work-around that compensates by subtracting one second before
calling mktime(3C) for years 1969 and earlier.

Fixes mktime_zone() on eg Solaris 8/Sparc with 32-bit ABI.

Note that eg Solaris 11 has altzone and is thus not affected.

Fixes truncation issues when time_t is larger than 32-bit.

Fixes testsuite failure for mktime(gmtime(-1<<33)).

There was a 32-bit singed integer overflow in the seconds offset
when the year offset got past 56 years.

Fixes testsuite failure.

gmtime(), localtime() and mktime() now attempt to support negative
timestamps on NT and AIX.

Fixes multiple testsuite failures.

tzset() needs to be called after altering the $TZ environment variable.

This caused mktime() on WIN32 to fail on times near
1970-01-01T00:00:00UTC as it does not support negative
timestamps.

Also fixes potential issue where putenv() may have overwritten
the saved old value for $TZ.

* patches/precompile-autodoc:
  Tools.Standalone.extract_autodoc: Fix typo in sscanf pattern.

* patches/precompile-autodoc:
  Tools.Standalone.extract_autodoc: Fix broken cmod precompilation.

When the precompiler was called by extract_autodoc, it was not
provided the --base argument, which in turn caused it to sometimes
generate *.c-files that were uncompilable. extract_autodoc now
attempts to derive the base argument in the same way as the usual
Makefiles do.

The zero confuses Sql.sql_util.handle_extraargs(), which causes
a bad call of sprintf(), which may fail with obscure errors like:
"Unfinished pad string in format string."

Fixes some of #10127.

This code has been broken since it was introduced in 2014...
