va_list family functions missing in latest Ndless ?

Here's what make tells me when building the nKaruga source (online version slightly outdated, ask for precision if needed) :

(right after a make clean)

$ make
mkdir .depends

I only include <libndls.h> in n2DLib.h . Is it that libndls.h doesn't include stdarg.h ?

EDIT : yeah. Can someone delete this thread ?

Did you get this fixed and what was the issue if you did? (in case this can be useful to other people)
In case you are wondering where I went, I left Omni back in 2015 to form CodeWalrus due to various reasons explained back then, but I stopped calc dev in 2016 and am now mostly active on the CW Discord server at https://discord.gg/cuZcfcF

I asked ExtendeD about this, and said I had to include stdarg.h in my own files as some standards had changed. Now that I added #include <stdarg.h>, everything works fine.

Yeah, it's considered bad code style to depend on other header files to include needed declarations for this reason.
