>Description:
	Package does not compile with gcc 3.4.0. Most of the problems come from
	NetBSD not implementing all the required math function for type long 
	double (supported in 3.4.0 but not NetBSD's system compiler). Other
	problems come from more thorough semantic checking in 3.4.0. The
	missing long double function problem can be rectified by using the
	functions in libstdc++v3 (if available); this is the approach taken in
	my supplied pathes.
>How-To-Repeat:
	Build with wip/gcc-3.4
>Fix:
	Apply the followwing patches:
