+ If you are cross-compiling<indexterm><primary>cross
+ compilation</primary></indexterm> (compiling on one architecture
+ with the intent to run on a different architecture), special care
+ needs to be taken. First of all, specify the host architecture
+ (the architecture PostgreSQL will run on) using the option
+ <option>--host</option>. The variables <envar>CC</>,
+ <envar>CFLAGS</>, etc. should refer to the build tools for the
+ host architecture. During the build process, the time-zone
+ database for PostgreSQL is created and a special tool to do that
+ is compiled and run during the build process. This tool needs to
+ be compiled using a native compiler. Specify this compiler using
+ the variable <envar>CC_FOR_BUILD</envar>. Cross compilation
+ requires expert knowledge and the support for this process in the
+ PostgreSQL tree should be considered somewhat experimental.
