fallback.cpp:
- wcstod_l

proc.cpp:
- job_t::get_processes

wutil.cpp:
- fish_wcstoll
- fish_wcstoull

Also drop unused configure checks/defines:

When using curses, look for libterminfo as well. (#9794)
Supports NetBSD, where libtinfo isn't available but libterminfo is.

11f954e7ec Correctly query termios.h and ioctl.h for struct winsize
The previous check was including these as relative includes, meaning the actual
system header files weren't actually being explicitly included and the check
could spuriously fail.

CMAKE_EXTRA_INCLUDE_FILES doesn't seem to have a way to specify that the
includes should be treated as system/global includes and CHECK_TYPE_SIZE() isn't
documented as being affected by any other variables that do, so switch to
another method altogether.

This requires that `struct winsize` have a member `ws_row`, but as best as I can
tell that is always the case.

Closes #9279.

379ad245e4 cmake: defeat bogus missing-field-initializers warning on g++ 4.8
g++ 4.8 emits a bogus warning on code like foo{}. Add a compiler flag
-Wno-missing-field-initializers if that warning is detected, because it

793aff3891 Use -fno-c++-static-destructors
Static destructors cause the destructor for a global object to run when
the program exits. They are bad because:

1. Registering them takes time and memory at startup

2. Running them takes time at shutdown and also they may have weird
   interactions.

This shaves about 12k off of the binary size.

Unfortunately gcc does not support this flag.

372f03ba20 Fix sys/sysctl.h depreciation error under glibc 2.30+
glibc 2.30 and up emit an ugly depreciation warning on
`#include <sys/sysctl.h>` - this patch makes the build system fail the
include test for `sys/sysctl.h` by forcibly setting `-Werror` before the
call to `check_include_files` (which internally uses `try_compile`) to
get `HAVE_SYS_SYSCTL` to not be defined (even if it's there) if it would
cause such a depreciation message to be emitted.

Ideally, we would not have to manually massage `CMAKE_C_FLAGS` before
calling `check_include_files` and could just tweak that to either always
or conditionally try compilation with `-Werror`, but try_compile doesn't
actually use any overridden `CMAKE_C_FLAGS` values [0] (dating back to
2006).

Always use LC_NUMERIC=C internally (#8204)
In most cases, like math, we want C-semantics for floating point
numbers. In particular "." needs to be the decimal separator.

Instead, we pay the price in printf, which is currently the sole place
to output in locale-specific numbers and attempt to read them and
C-style ones.

f9def20180 Update ConfigureChecks, only do the mtime hack for Linux.. on Linux
- Only check for HAVE_CLOCK_GETTIME and HAVE_FUTIMENS on Linux, since
they are only used to implement a Linux-specific workaround related
to mtime precision.
- Make sure that hack is limited to Linux builds
- HAVE_SYS_SYSCTL_H was unused, but we should have been using it
- HAVE_TERMIOS_H was unused, remove it

The only functional change is that unix machines with clock_gettime
and futimens will not bother with a Linux-specific hack, and won't
waste time checking for either during cmake configuration either.

9b763581cf cmake: Only check mbrtowc on Apple
The only thing we know ever triggered this is old macOS versions,

shouldn't be a common thing on macOS.

d8af0d2eec Stop creating a "build," directory
This was a typo. CMake doesn't take comma-separated arguments, but if
you do add the comma it tends to work, because it just takes that
comma as part of the string. So if it takes a directory to work in,
that it will then create, and you pass

${CMAKE_CURRENT_BINARY_DIR},

well, that might just create a "build," directory.

56c64281bd Update -latomic check to match the one in LLVM.
It's not entirely clear why the existing check does not work, but it seems to pass on clang++ even without -latomic, but causes the fish build to fail later.

Confirmed that with this change, g++ does not use -latomic, while clang++ does, and fish builds fine with both.

4a5f0f3a3d Fix missing references when manually linking against curses
When CMake's own curses logic fails to find curses/ncurses, we fall back to
pkg-config and manually link the required libraries. Some platforms (RHEL 6,
see #6587) require CURSES_EXTRA_LIBRARY=tinfo, so we link against libtinfo
if it's found but are happy to continue without it if it doesn't exist.

45633f4a54 cmake: force C++11 in CHECK_CXX_SOURCE_COMPILES for atomic
GCC 4.8 requires the use of `-std=gnu++11` or similar to enable atomic
features. However, older versions of CMake don't pick up the
project-wide target for C++11 when building the configure check targets.
Although CMake policy 0067 could be set to NEW to enable this, it only
exists on CMake 3.8 and newer, while many of our supported platforms are
on an older version.
