How to use ggc turn a progam from c++ to pure C

lnzju breastle was: How to use ggc turn a progam from c++ to pure C

First of all, it was once possible to run the C++ compiler which produced illegible C code and stop it before it pumped it through the C compiler and then the optimizer (if separate) and then the linker. If you ever saw the stuff, you would never want to do it. C++ is a much different language from C, and to force a C compiler to manage that, what with multiple inheritance, operator overloading, etc., makes the most gawdawful C code you ever saw.

Perhaps Microsoft do this with their C++ programs: convert them to C so that no one who steals the source code would be able to make head or tail of it.

You could stop it and get buttembler code if you could stand it by using the -S flag. Try it once: you will never do it again. Here is near the beginning of the buttembler output from a trivial, under one-page mostly comments, program:
