gcc NULL strings passed from ternary operators in kernel modules

interesting case with gcc. The following code example:
printk("%s\n", (value & 1) "set": "clear");
will evaluate to NULL unless the ":" character has a space after
static string declaration.
this version
printk("%s\n", (value & 1) "set" : "clear");
works.
go figure. Looks like gcc assumes this case is a C++ construct of
some sort and
evaluates it to NULL.
