45 <para>If you are building for 32-bit x86, but you have a CPU which is
46 capable of running 64-bit code <emphasis>and</emphasis> you have specified
47 <envar>CFLAGS</envar> in the environment, the configure script will
48 attempt to configure for 64-bits and fail.

53 <note>
54 <para>The default settings of GMP produce libraries optimized for
55 the host processor. If libraries suitable for processors less
56 capable than the host's CPU are desired, generic libraries can be
57 created by running the following:

104 <caution><para>The code in gmp is highly optimized for the processor where
105 it is built. Occasionally, the code that detects the processor misidentifies
106 the system capabilities and there will be errors in the tests or other
107 applications using the gmp libraries with the message "Illegal
108 instruction". In this case, gmp should be reconfigured with the option
109 --build=x86_64-pc-linux-gnu and rebuilt.</para></caution>
