Description d.binderman 2003-11-24 11:39:39 EST 
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)

Description of problem:

I just tried to compile package gsl-1_4-1 from Fedora.

The compiler said

1.

bessel_y.c(84): warning #239: floating point underflow
bessel_y.c(84): warning #239: floating point underflow

The source code is

  else if(1.0/GSL_DBL_MAX > 0.0 && x < 1.0/GSL_DBL_MAX) {

I am not sure what a fix for this might be.

2.

coulomb.c(994): remark #592: variable "G_lam_G" is used before its 
value is set
coulomb.c(996): remark #592: variable "Gp_lam_G" is used before its 
value is set

This seems to be a problem in some "can never happen" code. I'm not 
sure
what the fix is for this.



Version-Release number of selected component (if applicable):
gsl-1_4-1 

How reproducible:
Always

Steps to Reproduce:
1. compile the program
2.
3.
