is not needed any more with current versions of FreeBSD.
(Entries 52410 and 52412 in the Bug DB)

That change is based on Dan Nelson replying on the
FreeBSD mailing list, freebsd-questions@freebsd.org
in a thread running from 2010-Apr-29 to 2010-May-1 titled
    "Need info about FreeBSD and interrupted system
     calls for MySQL code"

Also, ensure the cmake settings correspond to the autotools
ones: Add "HAVE_BROKEN_REALPATH" to cmake.

cmake/os/FreeBSD.cmake:
  With current versions of FreeBSD, threading is not done on
  the user-level any more, so the huge "net retry count"
  is not needed any more.
  However, it is still being kept for now, so that it can be
  re-activated should the need arise.
  
  In addition, set "HAVE_BROKEN_REALPATH" to completely
  mirrot the autotools path.
configure.in:

 - Set SIZEOF_VOIDP the same way as others

 - Removed duplicate SIZEOF_SIZE_T setting
 - Added missing value for HAVE_CHARSET_ascii

configure.cmake
 - Added HAVE_ prefix to library names, like HAVE_LIBM
 - Set HAVE_CXXABI_H if header is found, HAVE_ABI_CXA_DEMANGLE
   controls if useful
 - Set SIZEOF_VOIDP the same way as others

 - Added missing HAVE_SYS_TIMES_H, HAVE_SYS_TIME_H, HAVE_TIME_H,
   HAVE_TIME and HAVE_TIMES
 - Removed most #if constructs, keep logic in "configure.cmake"
 - Use space after # if inside #if, for consistency

configure.cmake
 - Added MY_CHECK_TYPE_SIZE function that sets both SIZEOF_* and HAVE_*
 - If "sys/stream.h" exists, include it before "sys/ptem.h" in test
 - Set VOID_SIGHANDLER if RETSIGTYPE is set to "void"

Remove 'ROOT' from sql-bench dir variable, it's unnecessary.

Try to fix ia64/icc builds.

to a later release.

package, is more of a linktest of the embedded library.

Build full debug release in RPMs so we can include bits we need.

Fix libmysqlclient_r symlinks.
