glibc 2.2.5 problem solved

[M. Shell]

 Hello, 
 
 I sent in a bug report a day or two ago and I wanted you to know that I
fixed the problem that I had with glibc 2.2.5 make check.
 

My system is a: Red Hat 6.0 on 400MHz K6-2 with 256MB, 
Linux kernel version 2.4.1

current glibc 2.2.1
make 3.79
gcc 2.96
binutils 2.10.91
texinfo info 3.12f
awk 3.0.3
perl 5.005_03
sed 3.02
autoconf 2.13
gettext 0.10.38-7


glibc addons: Linuxthreads

configure:

./configure --enable-add-ons --with-headers=/usr/src/linux/include --prefix=/usr

then:

make

All went well. Then:

make check

then:


gcc test-tgmath.c -c -O2 -Wall -Winline -Wstrict-prototypes -Wwrite-strings -g  
 -fno-builtin  -Wno-uninitialized -D__NO_MATH_INLINES

showed up. This appears to be the same as Gnatsweb problem report #2925.

I then upgraded to Red Hat's gcc-2.96-85, which fixed the previous
problem. [So, Red Hat users should use gcc-2.96-85 or later, gcc-2.96-54 will
fail at make check. I don't know if gcc-2.96-69 will work or not.]

Now the only problem I have is:

make check

Test suite completed:

But, I _think_ this may be acceptable.


 Thank you,
