# Same class of bug as spades: mmseqs2 (vendored inside metaeuk)
# uses fixed-width int types (uint32_t/uint64_t/...) all over the
# place but relies on getting <cstdint> transitively from whatever
# standard header happened to pull it in on older GCC -- GCC 14's
# libstdc++ doesn't. A static scan found 47 affected files, way
# too many to patch one by one and too easy for a 48th to slip
# through later. Force the header into every translation unit at
# the compiler level instead of chasing individual includes.
# <cstdint> is the C++ wrapper header, not visible to the plain C
# compiler -- the equivalent for .c files is <stdint.h>.
