Thank you for solving the C99 issues. I have one minor issue with finite(x) on Microsoft VC++.
I had thought that GSL uses finite(x) throughout for this internally but defines it as isfinite(x) when this is available. Otherwise finite(x) is mapped to gsl_finite(x) to allow an architecture specific implementation to be provided.
However cquad.c uses isfinite(x) directly and hence bypasses the alternative version when isfinite is not available (which it isn't in VC++) and causes a linking failure.
I can cope with this but I am wondering whether I have to cope with both finite(x) and isfinite(x) use within GSL.
best regards, Brian Gladman
