Some compiler target like arm-linux\riscv\power\s390x\xtensa-gcc handle
char as unsigned char, then there are no warnings occur and got FAIL cases.
Just change the type char into explicit signed char to keep the feature
consistency.
gcc/testsuite/ChangeLog:
* c-c++-common/Wconversion-1.c: Update type.

So this is OK for trunk? Happy to commit it if you'd like, just wanted
to make sure as I'm not seeing it on trunk.
