Change the precompiled header so it doesn't use MSL Headers.  I forget
the exact which one but you'll find where it is defined if you check on
it.

MSL is the Standard Library,  but you probably mean the BSD lib and it's
POSIX functions.

Anyway it is simple to do, change the access path order and change the
define in one of PowerPlants prefix files.

What I'd do is create a copy of that header with the change and create
your own precompiled header source (.pch++) file so it doesn't bite you
later.

If you need detailed information or the exact header and line to change
let me know and I'll dig it all up.

1) Get rid of all the MSL access paths and replace them with system access
paths, and turn on 'Require Framework Includes'. My System Paths in Access
Paths pane then looks like

( ) {OS XVolume}usr/include
( ) {OS XVolume}usr/lib
(f) {OS XVolume}System/Library/Frameworks
(r) {Compiler}MacOS X Support

where ( ) is not recursive, (r) is recursive, and (f) is that little
frameworks script f. (Yes, this is Mach-o, I figure if you're doing a CFM
project you probably want OS 9 compatibility, and that means you're going to
use MSL, right?)

2) Lose all the MSL libraries and replace them with

usr/lib/crt1.o
MacOS X Support/Libraries/Runtime/Libs/MSL_Runtime_Mach-O_D.a

3) That's pretty much it far as I remember. Here's the debug target .pch++,
the portions relevant to stdlib usage anyway, I believe most of these
defines are irrelevant now that MSL headers are rooted out completely but
they'll probably help you during the conversion process. The various pragmas
are just there because I like them on, I don't think they have any
particular affect on the BSD v. MSL question.

No guarantees of correctness made for these instructions past that they
apparently produce a functioning program for me, if anybody has any
corrections to make they probably know more than I do.
