+Now, run autoconf in the main directory and in the samples, demos
+and utils subdirectory. This will generate the OS/2 specific
+versions of the configure scripts. Now run
+ configure --with-gtk
+as described above.
+
+If you have pthreads library installed, but have a gtk version
+which does not yet support threading, you need to explicitly
+diable threading by using the option --disable-threads.
+
+Note that configure assumes your flex will generate files named
+"lexyy.c", not "lex.yy.c". If you have a version which does
+generate "lex.yy.c", you need to manually change the generated
+makefile.
