Yes.  I do this quite a bit.  Go to your C 6.00 install disk and
re-install it, telling it to build the OS/2 libraries.  Also have it
include the OS/2 compiler.  Afterwards, apply the 6.0a patch (if you
have a separate set of patch disks for the "a" revision).

You may want to delete the DOS isntalltion first, although this isn't
necessary.

The OS/2 executables will be placed in a .../BINP directory
The DOS executables will be placed in a .../BINR directory
The bound (both OS/2 and DOS) executables will be placed in a .../BINB directory

All libraries will be placed in one place: .../LIB
Real-mode (DOS) libraries will have names of the form ?LIBC?R.LIB
Protected mode (OS/2) libraries will have names of the form ?LIBC?P.LIB
One of the library sets (Real or protected) may be renamed without the
P/R suffix.  This will be your default library for the linker.

After installing, place the .../BINP and .../BINB directories on your
OS/2 PATH (in config.sys).  Place the .../BINR and .../BINB
directories on your DOS PATH (in autoexec.bat)

The other variables (like LIB, INCLUDE, HELPFILES, etc) should be set
in both config.sys and in autoexec.bat, since they are common to OS/2
and DOS.

Once this is done, you simply give the "CL" command to compile.  Your
default executable type will be either DOS or OS/2 depending on what
kind of session you run it from.  To force the other type (required if
you need libraries with the P/R suffix), you use the parameters "/Lp"
or "/Lr".  This way, you can compile DOS code from the OS/2 compiler
and vice-versa.

Use the LINK.EXE that came with OS/2 2.0.  It's of a slightly higher
version than the Microsoft LINK.EXE.  I renames the Microsoft LINK.EXE
to MSLINK.EXE, to allow me to use either one.

The NMAKE utility that comes with Microsoft C 6.0 is compatible
(mostly) with the Unix make utility, and is useful for compiling GNU
makefiles. 

The Microsoft compiler comes with all the headers and libraries you
need to produce OS/2 1.2 code.  OS/2 2.0 comes with rc for compiling
resources in, and it also includes the icon editor.  You do not have a
font editor or a dialog box editor.  The IBM OS/2 2.0 toolkit has
these and lots of other stuff.

The Microsoft on-line help (QuickHelp) does not include the OS/2 API
reference.  You must get the Microsoft OS/2 1.2 toolkit for this.
It's been discontinued, but you may be able to find a copy at some
stores or computer flea markets.

If you can find the IBM OS/2 1.3 toolkit, I believe it'll have the
headers and libraries to produce OS/2 1.3 code.  But there aren't too
many new API's in it, so it may not be necessary.
