My newest todays build of gcc-6.1.0 with only 2 source lines added ('#ifndef __DJGPP__' and 
'#endif') which disables
one pre-processor internal performance optimization seems to work OK under Win10. It is additionally
built under Win10 with one additional bootstrap step (bootstrap4) for more torture. There was one 
unrelated
problem which caused .info files missing. I'll hopefully make next build available.
