  WML was written with portability in mind (one of the reasons its major parts
  are written in Perl and ANSI C). Additionally to overcome the system
  dependend characteristics WML uses a GNU Autoconf based configuration scheme
  which tries hard to determine the information both from the installed Perl
  interpreter and from scratch via own GNU Autoconf tests.

  So WML already compiles out-of-the-box on a lot of systems. At least the
  following Unix/Compiler/Perl variants were sucessfully tested by the author
  in the past:

  System        Platform   Perl     Compiler       Testhost    Time     WML
  ------------- ---------- -------- -------------- ----------- -------- -----
  FreeBSD 2.1.5 i586/166   5.004_04 pgcc 2.7.2     en1         14.11.97 1.3.5

  IRIX 6.2      IP20       5.004    SGI cc         sgihalle13  27.10.97 1.4.1

  If your Unix derivate is not on this list, don't panic. As we said, WML
  tries to determine the information itself, so there is a good chance that
  WML finds alternatives even for your system. At least for the compilation of
  ePerl the GNU autoconf does a trick: It don't tries to find a reasonable
  compiler and reasonable flags for it. Instead it uses the one your Perl
  interpreter was compiled with. Because the Perl 5 Porters already tried hard
  to determine the best combination, so ePerl can only benefit from it.

  If it still fails to compile or run, first try to see where the problem
  resides. Usually problems can occur when you are using a brain-dead compiler
  or a too old Perl version. Try to upgrade or use better variants.
