* For MS-Windows, take the file win-pl.zip. This is a binary distribution. There is no need to get the sources if you don't have the 32-bit WATCOM compiler or intend to do a lot of work porting the thing. * Versions 1.8.9 and later are written in pure ANSI-C. For old K&R C-compilers, stick with 1.8.8. There are no diffs between 1.8.8 and 1.8.9 as these would be enormous.
