Just to make sure I understand correctly. Your goal is to rewrite the
code from c99 to c++11 and not c11?

Well all the plugins in ams.lv2 are coded in c++ and are compiled with the c++11 standard.

But when ported the FFT Vocoder, it only compiles when using the c99 standard.

So I guess yes, I would like to rewrite the code from c99 to c++11.
