So, my first question is: am I mistaken in thinking that using
-std=c99 will help, portability-wise ?
It is often expected that requesting a specific standard at
compile-time will aid with portability. Usually the results are the
opposite of that because the standard requires that interfaces not
specified by the standard are not exposed and are therefore not
usable. Likewise, if a system does not support the standard, the
result is usually utter failure. It is typical that there are
multiple conflicting standards supported by the OS and requesting one
breaks use of the other.
