Just a complement on this issue: I installed an older version of GSL
(1.8, available in Debian etch) and I could confirm the bug that you
reported:
$ ./test

I will have a look at the specific GSL problem you mentioned.
This is what I obtain with the current version (1.15+dfsg.2-2) of the
Debian libgsl0 package:
$ cat test.c
#include <gsl/gsl_cdf.h>
#include <stdio.h>
main ()
{
printf ("%f\n", gsl_cdf_fdist_Qinv (0.01, 1, 10000));
}
$ gcc -o test test.c -lgslcblas -lgsl
$ ./test
6.637430
It seems that the problem you are fixing in Praat is actually a
non-bug in this version of GSL.
Did you spot other wrong results with GSL?
Cheers,
Rafael
