figinset.C question

[Angus Leeming]

In order to compile figinset.C with Lars' namespace anon in place, I have to 
move the function below outside of the namespace. 

My question is one about the comment. Is this function one that xforms should 
define, but was forgotten from the header file <forms.h> ? If so, I'll state 
that explicitly in the comment.

// xforms doesn't define this
extern "C"
