trunk libjava build failure in natTimeZone.cc?

[Boehm, Hans]

I'm seeing the following on the trunk.  Are others seeing this, too?  It seems to me that stdio.h should be included somewhere to use sprintf.  Was that the intent?

../../../gcc/libjava/java/util/natTimeZone.cc: In function `java::lang::String* 
   getSystemTimeZone()':
../../../gcc/libjava/java/util/natTimeZone.cc:86: `sprintf' undeclared (first 
   use this function)
../../../gcc/libjava/java/util/natTimeZone.cc:86: (Each undeclared identifier 
   is reported only once for each function it appears in.)
