1.19 The `configure' shell script attempts to guess correct values for
1.20 various system-dependent variables used during compilation. It uses
1.21 those values to create a `Makefile' in each directory of the package.
1.22 It may also create one or more `.h' files containing system-dependent
1.23 definitions. Finally, it creates a shell script `config.status' that

1.203 +Variables not defined in a site shell script can be set in the

1.205 +configure again during the build, and the customized values of these
1.206 +variables may be lost. In order to avoid this problem, you should set
1.207 +them in the `configure' command line, using `VAR=value'. For example:
