yes, it did.  because as i also explained previously, string.h is getting 
implicitly included by other files.  i never saw a warning related to this, nor 
crashes in the sim, and i still didn't after my change regardless of the 
config.h includes.  quoting behavior that *you* see on your outdated glibc has 
really no bearing whatsoever on my build system.

i'll take a look, thanks

the tconfig.h isn't really cruft, just not related to what autoheader outputs.  
it's target specific knobs for sim internals which shouldn't apply to the 
nrun.c interface.  clean up would be good, but i'll leave nrun.c alone atm 
since it matches what run.c is doing as you said.
