In general, it does.

The `C' runtime library takes care of this, for compiled `C' or `C++'
code; all the program ever sees, after a `read', is `\n'.  The only
problem I've ever seen occurs when I create an input file on Win32, move
it to Linux, and forget to convert CRLF --> LF.

It shouldn't have, (and I've never seen), any problem with LF only
input, (e.g. files moved from Linux without LF --> CRLF conversion);
files with CR only line endings probably would be problematic.

The particular failure, which triggered this discussion, is the result
of a bug in the MSYS shell, (fixed in the release candidate for our next
distribution).  It affects only the *building* of groff, not its
behaviour, once built.  There is a workaround for the bug, which is
completely innocuous for other platforms.  I know how to reproduce the
fault, so I'll apply the workaround to my working copy, and test on
Monday, before checking into CVS.
