[Bug-gsl] possible bug in GSL

[Gunjan Verma]

Dear GSL Team,
      I have found a potential bug in GSL, in the "infnan.c" file

I am building GSL for an embedded system which does not have isnan nor IEEE
comparisons, so both of those flags are 0 . As a result, based on the #if
and #elif statements both being false, I believe that the function gsl_isnan
does not get defined, because I am getting "undefined reference to
gsl_isnan" being generated by
svd.c when I try to use the svd .

I am not positive this is a bug because I have had to do some non standard
things to get the GSL to compile for the embedded system, but I wanted to
err on the side of caution and let you know.

Thanks for a great product,

Gunjan
