No one wants you to give up your compiler. It's the code not being
ISO-standard. The sense of a standard is to keep compatibility (I get a lot
of warnings with GCC3.2). And GCC 3.2 is pedantic to keep the standard as
violations can cause bugs and memory leaks ...

That means that code won't compile with future versions of more
ISO-compliant compilers. And more ISO-compliance is the aim of GNU GCC.
