The VSI C compiler is exactly the same frontend as on Alpha, Itanium, and the
cross-compiler.  It supports C99 (and has for a long time).  It is the RTL that lags
with C99 support but that should be available as an ECO today.

You mean make a x86-hosted cross-compiler for another LLVM target, like ARM
or Power?  Uh, I guess, but you'd need the language libraries or system libraries on
such a target.  Just compiling a BASIC program on x86 for an ARM target doesn't
do you much good by itself.  It wouldn't come close to linking.
