>From http://gcc.gnu.org/gcc-4.3/c99status.html , I see several features are still missing from gcc to fully adhere to the C99 standard. Those worth mentioning for me are complex support and variable length arrays, still there are other either missing or broken. This is of interest to me because I tend to try to follow standards so I usually compile my programs with -std=c99. Now, I wonder why after so many years of having a standard out, why there's still some c99 features missing. I can only imagine that there isn't too much incentive into implementing the missing features. The other possibility is that gcc, as a big software beast, is getting so big that adding completely new features might be quite hard... anyway, this is just me thinking out loud. I would like to hear what the current issue is with adding the missing features to gcc if anyone cares to explain.
