The Amiga version of GDB is buggy no matter which IDE you use. (It can't find the globals.)
If you can wait a while, it might be better to develop on AROS 68k and then run its version of GCC with debugger and then use ELF2HUNK on the executables to make them run on real AmigaOS. (I think Jason McMullan said he was going to write that utility.) Annotate isn't an IDE but it is a nice syntax-highlighting editor.
