Out of curiosity, why would you want to have a file of this number of code
lines?

>From a code maintenance point of view this would be an absolute nightmare to
maintain. Having followed the thread, I can't see you making any statement
as to what language the code is written in. Since the C compiler is
different to the C++ compiler, could this be a feature introduced by the
compiler rather than the linker?

My suggestion would be to split the one huge file down into a number of more
manageable chunks - say no more than 2000 lines per file excluding include
files. Even 2000 is probably too high (this is code only, not code and
comment lines). Pre C++, my company guidelines suggested suggested no more
than 200 lines of C code per file which seems at first to be ridicous, but
actually turned out to be a bit high on average. Using C++, there is no
suggested limit but I rarely find files execeeding 4000 lines code/comment
lines. I have no idea how many lines are introduced by MFC include files,
but they must add a fair few lines as well. My code mixes MFC and STL, and I
have yet to be unlucky enough to hit your problem. Perhaps it is somehow a
feature of producing a lib rather than a dll. As I vaguely recall, my one
brief experiment with LIB files failed when mixed with precompiled headers
in a workspace composed of separate dependent projects. This may be another
feature and nothing to do with your problem.

Good luck in your endeavours
