Fix compiler warning when using snprintf

snprintf is not defined in libc when compiling C89 code: it has been
standardized in C99 and POSIX.1-2001. Although the _POSIX_C_SOURCE macro
was defined with the correct value (i.e. 200112L), it was defined
_after_ the first inclusion, whereas it should be defined before the
inclusion of any header file. Hence the compilation warning.
