__sysconf and tcltk 8.3

[Jack Howarth]

Ulrich,
    What is the deal with __sysconf under glibc 2.1.97? Under earlier
versions of glibc 2.1.9x I was able to build RedHat's srpm for 
tcltk-8.3.1-46.src.rpm from RedHat 7.0. Now under glibc 2.1.97
I get the following error...

gcc -pipe -Wall  -rdynamic -Wl,-rpath,   -O2 -fsigned-char -D_REENTRANT -D_
TRING_INLINES -D__NO_MATH_INLINES tclXAppInit.o -L/usr/src/redhat/BUILD/tcl
3.1/tclX8.2.0/tcl/unix -ltclx8.2 -L/usr/src/redhat/BUILD/tcltk-8.3.1/tcl8.3
ix -ltcl8.3   -ldl  \
    -o tcl || (rm -f tcl; exit 1)
/usr/src/redhat/BUILD/tcltk-8.3.1/tclX8.2.0/tcl/unix/libtclx8.2.so: undefin
ference to `__sysconf'


This is under linuxppc with Linux 2.4-test10, gcc 2.95.3 and 
binutils 2.10.0.33. Is it possible that some change was made
to __sysconf for which a ppc specific modification wasn't 
applied?
                              Jack
