i believe there is. under a heading like "port missing kenc features
to gcc". the major missing feature is anonymous structures.

porting kenc to linux is doable, doesn't seem very useful, as
kenc doesn't do many of the stupid c compile tricks found
in linux heder files such as

__extension__()
__attribute__()

and my favorite

extern double atof (__const char *__nptr)
__THROW __attribute_pure__ __nonnull ((1)) __wur;

all care of stdio.h from the gnu standard library.
