When I asked this previously I should have mentioned that it's particularly a light-weight IDE that I'm after, so I’m having to ask again as a different question.
Something that is not just a text editor, is light-weight and versatile, that would suit Strawberry Perl, the GCC that comes with MinGW, GDB and Subversion. Something that when I want to use it is straight-away available, and is also fast to shut down preserving all my work. It doesn't matter if it's not a free or open-source program, what does matter is that it’s stable and is comfortable to use.
Maybe trying to have one IDE to use for both C and Perl is the wrong way to go about it - resulting in a solution that's not going to handle either one language or the other as well as a dedicated IDE would?
