gdb has it's troubles
such as not working with libnix compiled programs (I think, was a long time since I even tried gdb)
btw. StormC 4 is a lot more than simply a IDE
1) better compatability with both old StormC V3 and SAS/C
2) very good debugger (probably the best on the Amiga ever, beats the #### out of SAS/C's cpr and GG's gdb? puh)
3) very good documentation utilities(helps keep track of bugs, future requests also)
4) built in CVS
5) nice librarian
add to this that it is a GCC compiler together with stlport it's probably the best C++ compiler for the amiga (haven't seen anyone make stlport available for GG's GCC, which is a pity)
