Thanks for letting us know!
Could you provide more details? I assume you are building on Windows, right?
What are the exact compile errors you get?
That Unix98 check is fairly old. So the question is whether we should change
the check here, or something in our sources. Because on Windows you get more
and more POSIX APIs. Back then we simply considered its either UNIX(98) or
Windows.
For instance, chances are that stdlib.h is simply doing #undef _GNU_SOURCE
there, in that case this #include would just fight the symptom.

Hi Christian
I am using a Linux distribution (Mageia)
The actual version of Mageia is Mageia9
No problem to build LinuxSampler 2.4.1 with GCC 12.3
But we are preparing the next MAgeia10 inside Mageia Caludron
and Mageia10 will be built upon GCC15.2
That's where the problem appeared (GCC15.x is more strict)
The workaround was to modify configure.ac with a patch
adding only :
#include <stdlib.h> after line 133 That's enough
