Preprocessor question

Here's an easy question regarding preprocessor string-izing and subsequent
rescanning...
#define VAL 3
#define STR(x) #x
.
.
puts("val is " STR(VAL));
- - - - - - - -
Turbo C produces "3" for STR(VAL); Microsoft produces "VAL" and
leaves it at that.
Which behavior is correct? Further, if Microsoft's is correct, how can
one parenthesize a #define'd value to turn it into a character string?
