Update.
1998-04-16 07:42 Geoff Keating <geoffk@ozemail.com.au> * Makeconfig [!build-static]: Link `static' binaries with libc_pic.a. Still need *FLAGS-.o because we still sometimes build .o files. * db2/Makefile: Don't build libndbm.a if !build-static. 1998-04-16 07:42 Geoff Keating <geoffk@ozemail.com.au> * configure.in: New test for broken gcc on PowerPC. * sysdeps/powerpc/atomicity.h: Use result of test. * linuxthreads/sysdeps/powerpc/pt-machine.h: Use result of test. * math/libm-test.c: Update many of the epsilon to match actual performance. * sysdeps/libm-ieee754/e_exp.c: Reduce the number of branches. * sysdeps/libm-ieee754/e_expf.c: Likewise. * sysdeps/libm-ieee754/s_exp2.c: Likewise. * sysdeps/libm-ieee754/s_exp2f.c: Likewise. * sysdeps/libm-ieee754/e_pow.c: Correct typo. * sysdeps/powerpc/elf/libc-start.c: New file. * sysdeps/powerpc/elf/start.S: New file, use libc-start. * sysdeps/powerpc/elf/start.c: Delete. * sysdeps/unix/sysv/linux/powerpc/Dist: Remove syscall.h * sysdeps/unix/sysv/linux/powerpc/syscall.h: Delete. It was unused. * sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Correct previous few patches.
