I get:

cc -mt -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
-I./include  -DHAS_JIT -DSUN4  -o string.o -c string.c

cc: acomp failed for string.c
gmake: *** [string.o] Error 2

for this bit of code:

STRING *
string_concat(struct Parrot_Interp *interpreter, const STRING *a,
              const STRING *b, UINTVAL Uflags)
{
 ... some stuff ...
                b->flags |= BUFFER_neonate_FLAG;  /* <- modifies a const STRING * */
 ... more of the same ...
            b->flags &= ~(UINTVAL)BUFFER_neonate_FLAG; /* ditto */
 ... etc ...

Either this needs to not be const or some other consideration needs to be
made.
