I don't know how to remove this warning that is not raised by my compiler (gcc version 10.2.1 20201203). Maybe an array with an undefined length could solve this problem, but I know many C compilers would not agree!

Maybe just a matter of a #if __GNUC__ > 10 before the declaration of the array with undefined length (#else what is already present)? But that would also require a macro to define SIZEOF_U_PS_TEXT or something...

That may sound too much for "just a warning", especially when I get the warnings about Pango too (#111) :wink:

Anyway, I can provide with a PR if that may be useful, I have the code ready for review (I wanted to check this issue, go figure… :wink:)

I think the commit 92163a7 should solve the problem.

Okay :laughing: Fine for me.
