Hi All,

For long relative path still issue is there with Win10. 
Also tried longpath enable
(Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
\LongPathsEnabled set 1) but it is not working.

C:\Testing_ld\incresepath\incresepath\incresepath\incresepath\incresepath\
incresepath\incresepath\incresepath\incresepath\incresepath\incresepath\
incresepath\incresepath>C:/WindRiver/compilers/llvm-11.0.0.1/WIN64/bin/ldpentium.exe
-v
GNU ld (GNU Binutils) 2.34

Without fix:-
============
C:\Testing_ld\incresepath\incresepath\incresepath\incresepath\incresepath\
incresepath\incresepath\incresepath\incresepath\incresepath\incresepath\
incresepath\incresepath>C:\Testing_ld\llvm-11.0.0.1\WIN64\bin\ldpentium.exe
incresepath\incresepath\incresepath\incresepath\incresepath\incresepath\
incresepath\incresepath\incresepath\incresepath\incresepath\incresepath\

With fix:-

C:/WindRiver/compilers/llvm-11.0.0.1/WIN64/bin/ldpentium.exe: warning: cannot
find entry symbol _start; defaulting to 0000000008049000

Please find the attached patch (relative_path.patch) which fixes this issue.

Also let me know if there is any other alternate way to handle this.

Thanks,
Jaydeep
