StormC v3
+Easy and Intuitive IDE
+Relatively good ANSI C model
+Reasoably compact code
-very bad C++ implementation
-poor optimizer
StormC v4
+better IDE
+distriburted make
+cvs
+gcc compiler engine (compatible with 2.95.3 at least)
+good C++ support in gcc mode (as good as 2.95.3, basically)
-some bugs in IDE
-some IDE features (not present in v3) not complete?
-bloated C++ executables in gcc mode, but not really SCs fault, gcc is the same.
I really liked both systems, StormC4 has been instrumental in moving old code from v3 through to gcc compability.
