From 345b0f6b999f2c0aa4303bedbeaeb2c71987e684 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Rewrite JROUND macro to multiply by 1e6 rather than divide by
 1e-6  and vica versa for the next operation. This is reputed to fix inline
 math optimization troubles in glibc-2.0.x. Regression tests still pass on
 libc/i686 machine.  Patch suggested by Matt.
