The recent changes did not fix this problem in flex

Engine/csound_orclex.c: In function ‘yy_get_next_buffer’:
Engine/csound_orclex.c:1082:18: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
Engine/csound_orclex.c:2381:3: note: in expansion of macro ‘YY_INPUT’
Engine/csound_orclex.c: In function ‘csound_orc_scan_bytes’:
Engine/csound_orclex.c:2940:17: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
cc1: all warnings being treated as errors
CMakeFiles/csound64-static.dir/build.make:5149: recipe for target 'CMakeFiles/csound64-static.dir/csound_orclex.c.o' failed

so I assume I have to ru with -Wno-sign-compare

I don’t seem to have this problem here with 

$ flex --version
flex 2.6.4

I built it from the sources. Not sure if it is an option for you.

I found and installed flex 2.6.0 but it made zero difference.  Ensured I 
delete *lex.c as well but I still got the same until #i remembered io 
delete the CMakeCache.txt file

https://github.com/westes/flex/releases/tag/v2.6.4

is where I got it.
