Not sure what ancient compiler it is (gcc 4.2?), but didn't like hb_zip SFINAE
apparently:

Not going to try to appease.
For some reasons djgpp doesn't understand "unsigned int" can be same
with one of uint*_t anyway so lets do that for it explicitly.
Just to note, our CI's djgpp is based GCC 7.2.0 and isn't old.
https://voidlinux.org/ is yet another and different distro written from scratch, thus completely eligible to have a bot here!
Seriously however not that useful yet however but I will try to overload it other tasks later, like our other bots.
No test yet also, couldn't install cairo-devel, will try to fix that later.
Their harfbuzz package source: https://github.com/void-linux/void-packages/blob/master/srcpkgs/harfbuzz/template
TARGET_OS_OSX was introduced only in late OS versions
so always returns as "0" on older systems.
if !TARGET_OS_IPHONE can work, as it returns as !0 on older
systems where TARGET_OS_IPHONE is not defined, but is not
specific
if TARGET_OS_MAC && !(defined(TARGET_OS_IPHONE) && TARGET_OS_IPHONE)
is both specific and accurate on all systems.
Fuzzer caught it:

I can't reproduce locally, but many of the bots are failing because of this
as well.
It's a pity that operator-> must return pointer. Ugh. Why?!
Not sure why I don't get it, but this warning:
warning: base class ‘struct hb_iter_fallback_mixin_t<hb_array_t<const OT::UVSMapping>, const OT::UVSMapping&>’ should be explicitly initialized in the copy constructor [-Wextra]
