I am currently trying to port version 1.2 of C++ to an Encore Multimax
running UMAX 4.2.

The Encore's C compiler will not accept switch statments whose case labels
are not all in the same block (as in example below).
(According the Umax manual, this is an anomaly found only in Portable C).

The cfront program outputs code like this in some occurrences of switch
statements in the c++ source (this occurs repeatedly in the compiler source).

Does anyone know of a fix which either fixes the compiler source so this does
not occur or post processor which takes these unbalanced blocks out?
Any information would be appreciated.

-------------- example ----------------

/* this is short example of the problem */
main() {
int i ;
for (i=1; i<4; i++)
    switch(i) {
	case 1 : {
	int i = 1 ;
	printf("%d", i);
	break ;
/* } should be here */
	case 2 :
	printf("2");
	break ;
	case 3 :
	printf("3");
	break ;
} /* this should be above */
    } ;
}
------------- end of example ----------
