Avoid duplicating defines in config.h and on command line

2018-10-01T22:50:13+00:00

config.h - remove all defines we never use

2018-10-01T22:50:12+00:00

(strictly speaking PACKAGE and PACKAGE_NAME are unused, too, but
 let's keep them for now)

CMake: keep defines in ConfigChecks.cmake

2018-01-28T15:03:40+00:00

Remove cmake checks for unused sys/ headers.

2017-06-15T08:50:53+00:00

Nothing tests these macros nor includes these files, so I don't think
there's any useful side-effect for checking that they exist.

Remove cmake checks for C89 headers.

2017-06-15T08:50:53+00:00

These are roughly equivalent to autoconf's AC_HEADER_STDC and even they
say that macro is obsolescent.

strings.h is not really a C89 header, but it defined some things that
are no longer needed [1]. And no file actually #includes it.

Remove duplicated build checks.

2017-06-15T08:50:53+00:00

Most of these #defines are not even checked anyway, though they could
have the side-effect of failing configure before the build started.
However, these checks are redundant due to other checks for the same
thing:

* concept_check.hpp was added to Boost in 1.19.0, released in 2000. I
  sincerely doubt anyone is using that version right now, but I added a
  minimum version to the find_package() call. In any case, no code
  actually checked the #define, so it wouldn't have built without it
  anyway.
* FindBoehmGC puts gc.h on the compiler search path, so there's no need
  to try gc/gc.h also.
* libintl.h is found by FindIntl.
* unordered_set is part of the C++11 standard.
* zlib.h is found by find_package(ZLIB).
