Gerne, bare det er ISO-C99 og POSIX. Alt er nemlig lavet fuldstændig
efter standarderne!
Men hvilken native compiler overholder/følger standarderne?

Bare for at nævne et par stykker:
intmax_t, double_t, infinity, VLA, compound literal, variabel
erklæringer med block-scope (ikke function scope) og en sjat mere.
Stortset alt der er nyt i C99 i forhold til C89 anvendes, så down-grade
er reelt ikke en option.
Fx. kan jeg ikke bruge gcc 2.9x.x!
