Description
Alternative operator name keywords like `and`, `or`, `xor`, etc., are uncommon in MariaDB and can cause obscure build errors when the GCC flag `-fno-operator-names` is applied.
Description of `-fno-operator-names` https://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Dialect-Options.html:
Do not treat the operator name keywords `and`, `bitand`, `bitor`, `compl`, `not`, `or` and `xor` as synonyms as keywords.
In 11.0 this line of code was introduced in commit https://github.com/MariaDB/server/commit/b66cdbd1.
`DBUG_ASSERT(sel >= 0.0 and sel <= 1.00001); `
The build errors are as following, only the first line is pointing to the problematic line. Other errors are all misleading.
