Multiple definition of const RLUTIL_STRING_T ANSI_CLS[...]

[bitsycore]

Hello,
I tried to use rlutil.h in C, but when I include it in multiple file, "const RLUTIL_STRING_T ANSI_[..]" have multiple declaration, so I had to make a rlutil.c with the declaration of the variables and making them extern on the header.

for the .h extern const RLUTIL_STRING_T ANSI_CLS;
for the .c const RLUTIL_STRING_T ANSI_CLS = "\033[2J\033[3J";

It is better explained on a answerd on my stack question.

The current implementation of rlutil.h defines these constants directly in the header, which leads to linker errors when included in multiple translation units. To resolve this without forcing users to create a separate .c file, you could mark these variables as static const or inline const if targeting C99 or later. Could you clarify if the project intends to maintain strict C89 compatibility, or would adopting static const be an acceptable fix to allow header-only usage?
