Comment(by mojca.miklavec.lists@…):

 Here's an explanation in pseudocode of what exactly the attached patch
 does:
 {{{
 /*
  * User can set one of the following flags <with_aquaterm_flag>:
  * --without-aquaterm / --with-aquaterm=no
  * --with-aquaterm[=yes] (default; uses either
 /Library/Frameworks/AquaTerm.framework or simply considers CFLAGS/LDFLAGS)
  * --with-aquaterm=/opt/local/Library/Frameworks
  */

     // may be {"yes", "no", <arbitrary string that means yes, but
 specifies PATH>}
     if (with_aquaterm_flag != NULL) {
         with_aquaterm = "yes";
     } else {
         with_aquaterm = with_aquaterm_flag;
     }

     if (with_aquaterm != "no") {
         aquaterm_libs = "";
         if (with_aquaterm == "yes") {

         }

         if (!file_exists(aquaterm_framework_path + "/AquaTerm.framework"))
 {
             warn("Framework '" + aquaterm_framework_path +
 "/AquaTerm.framework' doesn't exist.");
             aquaterm_libs = "";
         }

         // now check if the following program compiles:

         if (program_compiles) {

             if (program_compiles) {
