Failed to execute make command

[simon28li]

When I execute the make command, the package contains the following error. Can you give me some help?
In addition, the version I tested was 3.6

I would recommend updating to GCC 10.3 as its replacing 10.2. There could be some bugs in the version.

Its so bad,I still reported the same error when I used version 10.3.0 of gcc.

[hanickadot]

I'm testing the code with GCC 10.3 and it matches. Do you have some weird locale set?

[andreas-schwab]

The test is bogus. '\x80' is a valid char if char is unsigned.
