it for validity.
The current language affects expression parsing and evaluation
(FIXME: it might be cleaner to make the evaluation-related stuff
separate exp_opcodes for each different set of semantics. We
should at least think this through more clearly with respect to
what happens if the language is changed between parsing and
evaluation) and printing of things like types and arrays. It does
*not* affect symbol-reading-- each source file in a symbol-file has
its own language and we should keep track of that regardless of the
language when symbols are read. If we want some manual setting for
the language of symbol files (e.g. detecting when ".c" files are
C++), it should be a seprate setting from the current_language. */
