2347a65fe0 Clarify the comment about Linux distributions 
Red Hat Linux was discontinued by Red Hat in 2003. It would make sense
to address glibc-based Linux distributions rather than Red Hat Linux.

329a494783 Make forwarding macros friendly to indentation or style checkers 
Indention programs such as clang-format usually rely on the occurrence
of statement terminator, otherwise they are likely confused. The revised
forwarding macros do not contain semicolons character, which is friendly
to indentation or style checkers.

256eb97849 Avoid unnecessary symbol exposure with ELF-based systems 
GCC's default visibility is "public" but can be changed to
"hidden" with the argument "-fvisibility=hidden".

Tested with x86_64 / Ubuntu Linux 18.04 LTS:

[before]
$ nm -g -C libmimalloc.so | grep "T " | wc -l
142

[after]
$ nm -g -C libmimalloc.so | grep "T " | wc -l
93

This patch does not change the build on macOS.

855e2f0d89 Use clock_gettime() instead of timespec_get() 
clock_gettime(CLOCK_REALTIME, &ts) is equivalent to timespec_get(&ts,
TIME_UTC) in C11.

It has the advantage that avoids the following building error when building
with macOS:

  warning: 'timespec_get' is only available on macOS 10.15 or newer

a667971cbf Apple rebrands "OS X" as "macOS" 
In 2012, with the release of OS X 10.8 Mountain Lion, the name of the
system was shortened from Mac OS X to OS X. In 2016, with the release
of macOS 10.12 Sierra, the name was changed from OS X to macOS to
streamline it with the branding of Apple's other primary operating
systems: iOS, watchOS, and tvOS.
