[Bug-gsl] Re: error in manual

[Ivan Liu]

Hi, this is to cancel/correct my bug report.
What I meant was, while calling the macro one should use
GSL_FN_EVAL(&F, x)
instead of 
GSL_FN_EVAL(F, x)

maybe this is trivial for most people, but I got confused. So I'll let the 
maintainers
judge if further clarification in the manual is necessary.

Regards,
Ivan Liu
