LEMON 1.0 reported to compile on the following platform and compiler

= Linux =

 - GNU GCC
   - starting with 3.3, all recent compiler should be fine
     - tested with 3.3, 3.4, 4.1, 4.2, 4.3
   - version 2.95 is definitely not enough
 - Intel ICC
   - version 10.1 works well,
     - the highest warning setting ({{{-w2}}}) triggers infinitely many warnings/remarks, but none of them is a valid problem.
   - older versions don't seem to work due to deficient implementation of the standards (8.0) or serious compiler bug (9.1)

= M$ Windows XP =

 - Visual Studio 2005, 2008
 - Cygwin
   - work well from gcc-3.3 upwards.
