I've been using Watcom C/C++ since the mid 1990's. Thank God this masterpiece wasn't lost in the industry chaos and "designed by committee" insanity and Micro$oft's "let's lock 'em in" predation. I "bet the farm" on OS/2, on Watcom, and on the C++ language, and two of those three bets came through for me. As open source, the debugger became unstable. That appears to be fixed in this fork. What I like: (1) multiplatform. (2) open source. (3) simple, no-agenda copyleft license. (4) Tight, compact, efficient binaries. (5) Generated code that functions correctly. That is why IPDOS (tm) IdeaFarm (tm) Piggyback Distributed Operating System is strategically committed to Open Watcom.
Probably the nicest and most complete OpenSource toolset for the Win32API. Provides GUI editors for dialogs, strings, menus, accelerators, bitmaps, cursors, and icons. Provides a VI interface for the editor or allows the user to insert his own editor. Unlike other open source tool kits, this one just works.
Pretty nice improvements in v2.
