*
|

|
|
* 2002-04-13 lpd Removed support for non-ANSI compilers; removed references to
|
||
|
|
* Ghostscript; clarified derivation from RFC 1321; now handles byte order
|
||
|
|
* either statically or dynamically. 1999-11-04 lpd Edited comments slightly
|
||
|
|
* for automatic TOC extraction. 1999-10-18 lpd Fixed typo in header comment
|
||
|
|
* (ansi2knr rather than md5); added conditionalization for C++ compilation
|
||
|
|
* from Martin Purschke <purschke@bnl.gov>. 1999-05-03 lpd Original version.
