+Alternatively, Paul Smedley's ready-to-go GCC build environment has been known to

 To build, you should, if your environment is set up well enough, be able to just
 type `./configure' (or `sh configure' if you're using the OS/2 shell) and `make'.
 
+You may have to manually specify `--os OS2' on the configure command line, as
+configure cannot always detect OS/2 correctly.
