[tlbuild] dvisvgm error with LLVM/Clang

[Richard Koch]

Peter,

I just tried to compile the latest version of things on
Yosemite, the latest OS X system. This means the
compiler is LLVM/Clang.

I have an error in the log,

If I look at the file VectorIterator.h near line 100, I find that several previous
functions contain

	if ( valid() ) 
		…

and the error occurs when instead a function contains

	if ( valid )
		…

The problematic code reads

	size_t distanceToLast () const { 
		 if (valid) 
			 return _vector.size()-_pos-1;
		 return 0;
	 }

Ideas?
