Probably it was too late yesterday, because today I cannot get this
atomic64.h failure again (instead error: unknown type name ‘HttpProxy’).
Nevertheless, dropping 32 bit platforms might be reasonable because
upstream is not caring about them anymore, like mentioned in 2016 in the
issue "Please remove explicit -m32/-m64 switch" reported by you to upstream:
... We do have workaround code in all known places, but we no
longer test our code under 32-bits and ...
In the meantime bug [2] got opened in Debian against ncbi-vdb that
is exactly this issue about uint64_msbit found by Ubuntu with
the same proposed change.
Kind regards,
Bernhard
