Pelles C is a complete development kit for Desktop Windows. It contains among other things an optimizing C compiler, a macro assembler, a linker, a resource compiler, a message compiler, a code signing utility, a make utility and an install builder.

It also contains an integrated development environment (IDE) with project management, debugger, profiler, source code editor, and resource editors for dialogs, menus, string tables, accelerator tables, bitmaps, icons, cursors, animated cursors, animation videos (AVI's without sound), versions and manifests.
