Synopsis: _GLIBCPP_HAVE_MBSTATE_T breaks non-GLIB systems

Responsible-Changed-From-To: unassigned->bkoz
Responsible-Changed-By: bkoz
Responsible-Changed-When: Wed Jul  3 10:13:23 2002
Responsible-Changed-Why:
    Mine.
State-Changed-From-To: open->feedback
State-Changed-By: bkoz
State-Changed-When: Wed Jul  3 10:13:23 2002
State-Changed-Why:
    I'm surprised that you are using --enable-cheaders=c. Please provide more details on how you got this working for NetBSD. It is not a supported default configuration, although it does work for some targets (newlib crosses, perhaps QNX.)
    
    In any case, this patch below should do the trick. If it doesn't, you'll have to add more description to your bug report, including compiler error, sample code that goes wrong, and includes used...
