I've been working on a professional code project for the past few
months, and I've run into a pesky issue with the MSVC 7.1 (.NET)
compiler. I'm compiling a standard C++ console project, excluding MS
extensions (so hopefully compiling in normal ANSI mode). I'm using a
LOT of macros do some fairly tricky things, and it seems that I've run
into a limit on the length that a macro argument can be. By length, I
mean the textual length of the argument passed to the macro. For
example, using the macros LIST() and ENTRY() in the following way, I
encounter the issue:

LIST
(
    ENTRY(Value1)
    ENTRY(Value2)
    ...
    ENTRY(ValueN)
)

If I have too many ENTRY()'s inside the LIST() macro, the compiler with
throw the following error:

MyFile.h(122): fatal error C1001: INTERNAL COMPILER ERROR
        (compiler file 'msc1.cpp', line 2701)
         Please choose the Technical Support command on the Visual C++
         Help menu, or open the Technical Support help file for more
information

Well, that's a compiler bug for sure. You might try to increase the memory
allocated to the compiler, I think /Zm is the switch.

Two other options would be to use a different preprocessor (I seem to
remember that the Boost project has a C99 compatible preprocessor) or to
use abbreviations (though 'LIST' and 'ENTRY' are rather short by themselves
already.
