Does traditional C allow initializing a union?

(Okay this is a C question not an egcs one, but it relates to egcs code.)

	Does traditional C allow initializing a union?  Eg:

 > typedef union rtunion_def
 > {
 >   long rtwint;
 >   int rtint;
 >   char *rtstr;
 > } rtunion;
 > 
 > static rtunion foo = {0};

	This works under all ansi compilers I've found, but it fails for
me on SunOS4 cc and Irix4 'cc -cckr'.  Is there another way to
initialize a union?

	I'm trying to get emit-rtl.c: global_rtl.fld[] initialized by
using {{0}} (double nesting since its an array) and it doesn't work in
the traditional C case, (just as with the above code.)
