(*) gcc=53 now means gcc 5.4, and is hard to fix until we remove gcc=48
support and can go to eg, gcc=5, gcc=6, etc. the same applies for
the HAVE_GCC variable in the build system.
script from othersrc to usr.bin/sys_info
The sys_info script is a small script which will show the version
information for installed utilities. It also works on the kernel, and
on most libraries.
Its use is as follow:

The -a option can be given to the script to print out the information
on all known components.
The sys_info script also works on libraries, returning their
"versions" as given by the shared object version numbers.

Adding a whole extra header file just for this is not the optimal
solution... but stuffing it in with anything else exposes things that
otherwise wouldn't be.
Nothing in userland should use <sys/semaphore.h> directly, and if some
foolish third-party software should decide to do so anyway in spite of
the instructions to the contrary I will ruthlessly break it later when
the big kernel includes cleanup finally happens.

Heinz in 2008.
