========================================

Rather strange. When I build with MinGW (gcc-3.4.5) in my msys shell, 
there's no problem.

A diff on our configure outputs is attached (the '-' is what the OP had, the 
'+' is what I had). Perhaps that rings a bell for someone here .... doesn't 
ring any bells for me, but :-)

Perhaps of more siginificance is the contents of (the generated) 
gsl-1.15/config.h. You should be able to find the following line in that 
file:

#define HAVE_DECL_FINITE 1

And you should also be able to find this line:

#define HAVE_IEEE_COMPARISONS 1

Does your gsl-1.15/config.h contain those lines ? (Your configure output 
suggests that you should at least have the first.)

What does 'gcc -v' output for you ?

Cheers,
Rob
