Absolutely.  I haven't used it for a while but when I was compiling DOS 
programs I used the Borland command line compiler and assembler from the Unix 
command line using doscmd from the pkgsrc tree 
(ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc/emulators/doscmd/README.html) 
to run the commands.  I even created the following make (GNU make - not 
tested on BSD make) rules to handle this.  That way I can work entirely in 
Unix except for the actual command to compile, assemble or link.  Note that 
Borland command line utilities accept the Unix EOL convention so you can use 
your Unix editors and CVS/RCS/etc. utilities as well.
