[Bug classpath/24035] New: 64-bit unclean fdlibm code

[gbeauchesne at mandriva dot com]

Hi,

Kaffe's PrintDouble test fails on 64-bit systems. fdlibm mprec.c (lshift) can go
into an infinite loop. Part of the code still assumes "long" is a 32-bit value,
thus the patch (yet-to-be-attached) replaces some occurrences of long to int.

The better fix would probably be to audit uses of sizeof(long) vs. sizeof(int) +
replacing some of shift values computation to 8*sizeof(underlying type) instead
of using plain "32" but I don't think this ancient code is worth the effort.
