The only programming tool that can make targets for all three platforms is
Watcom C++, currently at version 10.5.  Watcom allows making cross-targeted
applications, for example compiling a DOS or Windows program under OS/2.

Borland C++ is available as two separate products, one for DOS and Windows
and another for OS/2.  They do not support cross-targeting, but the Windows
product supports both 16-bit and 32-bit Windows.

IBM Visual Age C++ is available as two separate products, one for 32-bit
Windows and one for OS/2, which also do not support cross-targeting.  No
DOS or 16-bit Windows compiler is available.

If cross-platform compatibility is your main concern, Watcom is a no-brainer.
