This would be a problem if you were compiling C source into Java
source; but AIUI the JVM is a pretty complete virtual representation
of an actual machine; you should be able to use all features you
normally have in C.

But it'd either have to be a freestanding (think "embedded")
implementation, or you'd need a decent implementation of the standard
C library in javacode.
