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.
