+* Building wxGTK on OS/2
+--------------------------
+
+Please send comments and question about the OS/2 installation
+to Andrea Venturoli <a.ventu@flashnet.it> and patches to
+the wxWindows mailing list.
+
+You'll need OS/2 Warp (4.00FP#6), X-Free86/2 (3.3.3 or newer), 
+Lesstif (0.89.1 or newer), emx (0.9d fix 1), flex (2.5.4),
+yacc (1.8), unix like shell, e.g. korn shell (5.2.13),
+Autoconf (2.13),  GNU file utilities (3.6),
+GNU text utilities (1.3), GNU shell utilites (1.12), m4 (1.4), 
+sed (2.05), grep (2.0), Awk (3.0.3), GNU Make (3.76.1).
+
+Open an OS/2 prompt and switch to the directory above.
+First set some global environment variables we need:
+
+SET CXXFLAGS=-Zmtd -D__ST_MT_ERRNO__
+SET CFLAGS=-Zmtd -D__ST_MT_ERRNO__
+SET OSTYPE=OS2X              
+SET COMSPEC=sh
+
+Notice you can choose whatever you want, if you don't like OS2X.
+
+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-motif
+as described above.
+
+To verify Lesstif installation, configure will try to compile a
+sample program that requires X headers/libraries to be either
+available via C_INCLUDE_PATH and LIBRARY_PATH or you need to
+explicitly set CFLAGS prior to running configure.
+
+If you have pthreads library installed, it will be autodetected
+and the library will be compiled with thread-support.
+
+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.
