c - Why are there few compilers that comply with C99? -


it's on ten years since c99 published. however, far there have been few, if any, compilers have support new features of c99. why?

btw: there compilers comply c99?

according wikipedia: c99 implementations, popular compilers (except visual studio) have support not c99 features(like gcc or clang), but, yes, compilers have comply c99.

i think 1 of reasons of c99 features not useful compiler vendors. newest standard, c11, on other hand, allows implementations not support parts of standard — including had been mandatory support in c99, complex types , variable length arrays. (see c11 §6.10.8.3 conditional feature macros)
