Well, nice hack (like Stefan's post mentioned) but conceptually
indiscutable. Imagine such a "solution" for something like svn:keywords
or svn:ignore (if it weren't implemented yet).

I think a new property is the only way of getting things right in this
regard. In our projects we have quite some files and file types that
*would* require such thing.

IMHO, there should be a property, named f.e. svn:merge-policy, that can
be set on a file to any of the following values:

default (the current behavior)
*none* (i.e. property not set, same as "default")
text-merge (forcing a text style even if mime type is binary)
no-merge (forcing binary behavior: fail on merge)
external[=name] (must use an external tool for merge)

maybe a couple of variants more. The "external" value is some kind of
clumsy but should assure that a specific merge tool (local to the
client, specified as a shortcut name, default if empty) is used. If this
shortcut name is not defined, the merge will fail automatically (or
fall-back to the "default" shortcut name). But this could be an item to
discuss, maybe other users bring up more/better options.

The next step is inter-file merge dependency. This could be implemented
with a new property named svn:merge-dependency.

For example, consider the following files:

functions.h
functions.c

In special environments it is necessary to disallow merges of
/functions.h/ if /functions.c/ has changed. So one would execute

svn propset svn:merge-dependency "functions.c" functions.h

to fail merges of functions.h in case of local changes to functions.c.
"Fail" could mean to behave like specified using the svn:merge-policy
property of the file.

And, of course, this is an SVN issue, not TSVN.
