In terms of functions calls, I don't think it makes a difference,

It makes the calling code a bit smaller, e.g., it avoids GCC having to
generate code to save and restore registers in the caller, along with
issuing two calls instead of one. Admittedly not a huge deal.
I also vaguely think that perhaps GCC will find the resulting code
easier to analyze. Although this is just a guess, GCC is kinda buggy in
this area and I hope the smaller code avoid bugs.
+ __gl_error_call (rpl_error, status, __VA_ARGS)
What is __VA_ARGS ? Did you mean __VA_ARGS__ ?
Yes I did. Thanks for catching that typo. I installed a fix.
