In case some of you missed it, there's a very obscure bug in the
NewFloatMgr.lib that came with CW R5. Here's the email from Eric
Cloninger...

Hello All,
Sorry for the long inclusion, but someone previously mentioned that context
is important...
If you are using the NewFloatMgr.lib that is included with CW/Palm R5, you
should stop and rebuild with the library that is on CW/Palm R4. The
library, which is provided by Palm and included on our CD, was not built
correctly. I'll spare you the details, but if you disassemble the two
libraries, you will notice the JSRs for the R4 and R5 versions are
different.
This change should affect very few of you. After all, it took four months
to surface in the first place. It is an issue if you are targeting Palm OS
1.0 users, have floating point code, and you are including NewFloatMgr.lib
from R5 in your projects.
