Linux/PPC problem with egcs-2.91.04 980115

Hi-

I tried compiling libc-980111 (from
/anonymous@alpha.gnu.org:/gnu/libc/libc-980111.tar.gz) and I got the 
following compilation error.  Here's my kernel version (in case it's
relevent):  

    Linux version 2.1.24 (root@powerstack.linuxppc.org) (gcc version
    2.7.2.1-ppclinux) #15 Sat Jan 3 14:29:30 UTC 1998 

Here's the compilation error:

    gcc ../sysdeps/libm-ieee754/s_isinff.c -c -O2 -Wall -Winline -Wno-parentheses -Wstrict-prototypes -Wwrite-strings -g     -Wno-uninitialized -Wno-write-strings -I.  -I.. -I../include -I../libio  -I../sysdeps/powerpc/elf -I../linuxthreads/sysdeps/unix/sysv/linux -I../linuxthreads/sysdeps/pthread -I../linuxthreads/sysdeps/unix/sysv -I../linuxthreads/sysdeps/unix -I../linuxthreads/sysdeps/powerpc -I../linuxthreads/sysdeps/pthread/cmpxchg -I../crypt/sysdeps/unix -I../sysdeps/unix/sysv/linux/powerpc -I../sysdeps/unix/sysv/linux -I../sysdeps/gnu -I../sysdeps/unix/common -I../sysdeps/unix/mman -I../sysdeps/unix/inet -I../sysdeps/unix/sysv -I../sysdeps/unix -I../sysdeps/posix -I../sysdeps/powerpc -I../sysdeps/wordsize-32 -I../sysdeps/ieee754 -I../sysdeps/libm-ieee754 -I../sysdeps/generic  -D_LIBC_REENTRANT -include ../include/libc-symbols.h     -D__NO_MATH_INLINES -D__LIBC_INTERNAL_MATH_INLINES -DNO_LONG_DOUBLE -D_Mlong_double_=double -o s_isinff.o

    gmake: *** [math/subdir_lib] Error 2

Does anyone know what this means?  Is it a bug in the compiler, or is
it a bug in the code?

            Thanks for any help,

                -Fred
