Would the following make sense as an enhancement, and still be standards
conforming?

RFE: If compiling in C99 mode at -O0 (optimization disabled), compile functions
declared as "inline" as if they were instead declared "static".

In this way, if a user makes use of inlined functions, but decides to
re-compile his program at -O0 (in C99 mode) he doesn't have to resort to using
work-arounds (such as compiling with -Dinline=static").
