You're right.  I meant the D standard library.  But Phobos' use of 
fprintf creates quite a few glibc dependencies, be they dynamically or 
statically resolved.  I'll admit that Tango does use fprintf with DMD 
for coverage and profiling output as well--this is a dependency I've 
been a tad too lazy to eliminate :-p
