Help with float tests

["Carlos Velasco" <carlosev at newipnet dot com>]

Hi,

Any help with this would be apreciated.
I have problems with make check in test-ldouble

I have compiled glibc from CVS.
Kernel: 2.4.19
Compiler gcc 3.1.1
CPU: AMD K6-2

outputs:

> uname -a
Linux atlas 2.4.19 #1 Tue Aug 6 01:59:40 CEST 2002 i586 unknown

Configure was:
configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-all-warnings --enable-add-ons=linuxthreads

When making "make check":

gcc -nostdlib -nostartfiles -o compile/glibc/comp/math/test-ldouble  -Wl,-dynamic-linker=/lib/ld-linux.so.2    compile/glibc/comp/csu/crt1.o compile/glibc/comp/csu/crti.o `gcc --print-file-name=crtbegin.o` compile/glibc/comp/math/test-ldouble.o compile/glibc/comp/math/libm.so.6  -Wl,-rpath-link=compile/glibc/comp:compile/glibc/comp/math:compile/glibc/comp/elf:compile/glibc/comp/dlfcn:compile/glibc/comp/nss:compile/glibc/comp/nis:compile/glibc/comp/rt:compile/glibc/comp/resolv:compile/glibc/comp/crypt:compile/glibc/comp/linuxthreads compile/glibc/comp/libc.so.6 compile/glibc/comp/libc_nonshared.a -lgcc `gcc --print-file-name=crtend.o` compile/glibc/comp/csu/crtn.o

The output of test-ldouble.out:
