About the only files that fall into this category are the EMX runtime DLLs. 
As Peter Knapper says, most OS/2 applications are distributed with all of the
DLLs necessary to run them as part of the bundle.

Applications compiled with EMX C/C++ are the exception.  Generally,
applications that use the EMX runtime DLLs are distributed without those DLLs, 
and the READMEs for the applications point one to EMXRT.ZIP on one's favourite 
files BBS or files site.

The parallel between EMX C++ and Visual BASIC is pretty much exact.  The
reasoning that EMX C++ developers give for not including the EMX runtime DLLs
in all packages that require them is the same as the reasoning that Visual
BASIC developers give for not including the VBRUN DLLs in all packages that
require them.  Indeed, the two sets of DLLs fulfil largely the same function.
