yes
(eg sdcc for microcontrollers, plan9 cc used for the go runtime)

probably no

i used some of them, i know ctags handles __restrict
while swig (1.3) does not

many of the c (and c++) parsing tools dont do correct
preprocessing or don't define all the macros like
__STDC_VERSION__ so even if c99 grammar is mostly
supported i wouldnt be surprised if doxygen or indent
or similar tools had problems with __restrict

the headers are not only for compiling musl

of course glibc uses __restrict so it should work
most of the time
