 2.12.5.7 SGI Irix Notes
 .......................
 
 If you are using Irix Version 6.5.3 or newer, `mysqld' will be able to
 create threads only if you run it as a user that has `CAP_SCHED_MGT'
 privileges (such as `root') or give the `mysqld' server this privilege
 with the following shell command:
 
      chcap "CAP_SCHED_MGT+epi" /opt/mysql/libexec/mysqld
 
 You may have to undefine some symbols in `config.h' after running
 `configure' and before compiling.
 
 In some Irix implementations, the `alloca()' function is broken.  If the
 `mysqld' server dies on some `SELECT' statements, remove the lines from
 `config.h' that define `HAVE_ALLOC' and `HAVE_ALLOCA_H'.  If
 `mysqladmin create' doesn't work, remove the line from `config.h' that
 defines `HAVE_READDIR_R'.  You may have to remove the `HAVE_TERM_H'
 line as well.
 
 SGI recommends that you install all the patches on this page as a set:
 `http://support.sgi.com/surfzone/patches/patchset/6.2_indigo.rps.html'
 
 At the very minimum, you should install the latest kernel rollup, the
 latest `rld' rollup, and the latest `libc' rollup.
 
 You definitely need all the POSIX patches on this page, for pthreads
 support:
 
 `http://support.sgi.com/surfzone/patches/patchset/6.2_posix.rps.html'
 
 If you get the something like the following error when compiling
 `mysql.cc':
 
      "/usr/include/curses.h", line 82: error(1084):
      invalid combination of type
 
 Type the following in the top-level directory of your MySQL source tree:
 
      extra/replace bool curses_bool < /usr/include/curses.h > include/curses.h
      make
 
 There have also been reports of scheduling problems.  If only one
 thread is running, performance is slow.  Avoid this by starting another
 client.  This may lead to a two-to-tenfold increase in execution speed
 thereafter for the other thread.  This is a poorly understood problem
 with Irix threads; you may have to improvise to find solutions until
 this can be fixed.
 
 If you are compiling with `gcc', you can use the following `configure'
 command:
 
      CC=gcc CXX=gcc CXXFLAGS=-O3 \
      ./configure --prefix=/usr/local/mysql --enable-thread-safe-client \
          --with-named-thread-libs=-lpthread
 
 On Irix 6.5.11 with native Irix C and C++ compilers ver. 7.3.1.2, the
 following is reported to work
 
      CC=cc CXX=CC CFLAGS='-O3 -n32 -TARG:platform=IP22 -I/usr/local/include \
      -L/usr/local/lib' CXXFLAGS='-O3 -n32 -TARG:platform=IP22 \
      -I/usr/local/include -L/usr/local/lib' \
      ./configure --prefix=/usr/local/mysql --with-innodb --with-berkeley-db \
          --with-libwrap=/usr/local \
          --with-named-curses-libs=/usr/local/lib/libncurses.a
