Forwarded from #882029. This function is found in format.h but it not exported in map-file and thus unavailable on most (all?) linux systems. I don't know if the function is supposed to be exported, or maybe it should be private instead. #882029: https://bugs.debian.org/882029
I'm 99.3% certain that it's supposed to be exported. It's documented, and internally it's only used in format.c, so if it isn't meant to be exported, then the declaration should be removed from format.h since it's not needed. Patch submitted: https://patchwork.freedesktop.org/patch/192885/
The patch is now in master.
