Since I'll probably support Guile in mingw-cross-env for a long
time, I'd like to find a solution that doesn't require such a
bad hack.

What about a read-only variable that is initialized on Guile
initialization or as an initialized constant?

Or, what about changing the generated code? Why does the generator
have to determine a number to be written into the generated code?
Instead, the generated "scmconfig.h" could contain code like this:

    #include <uniconv.h>


    #define SCM_ICONVEH_ERROR iconveh_error
