On WIndows Vista Business SP3 I'm getting when LFN=N (the same system I'm using to build GCC ports 
of GCC):

bash-2.05b$ echo '#include <iostream>' | gcc -std=c++17 -x c++ -

    48 | # include <string_view>

       |           ^~~~~~~~~~~~~

compilation terminated.


DJGPP unzip32 unpacked string_view as string.view and as result it is not found. This problem is 
not detected by doschk and similar programs (I used my own test implementation when building 
gcc-10.2.0 for DJGPP). There are more similar problems visible in include/cxx/10 directory (I did 
not check subdirectories now)


This could be fixed by renaming files and adding rules to corresponding header.gcc files
