_FPU_SETCW is undefined in libc5

[OKUJI Yoshinori]

  Hello,

  I compiled and checked gsl-0.6 on i586-pc-linux-gnulibc1, and I
found one problem in it. In "ieee-utils/fp-linux.c", _FPU_SETCW is
used unconditionally, but the macro is not defined in libc5,
unfortunately. So I had to patch the file, to run the tests. Here is
the patch:

--- gsl-0.6/ieee-utils/fp-linux.c.orig  Mon Jun 12 06:37:35 2000
+++ gsl-0.6/ieee-utils/fp-linux.c       Mon Jun 12 05:57:32 2000

 int
 gsl_ieee_set_mode (int precision, int rounding, int exception_mask)
 {


  I just copied the definition from glibc-2.1.3. Although I don't
think the patch is very good, I hope that I've made it clear what is
my problem.

Thanks,
Okuji
