see mail "Re: problem with config.h" from Martin Sebor:
Yes, the name is far from ideal. I've been thinking about making it configurable, perhaps by replacing the _RWSTD_USE_CONFIG macro with _RWSTD_CONFIG=<config-header-pathname>. The patch below has all the source changes necessary to make it work (the rest of the changes need to go in the makefiles and VisualStudio scripts).
I suggest you create an enhancement request in Jira for this to help us remember to get it done.
