It turns out the macro is never used, anad <stdint.h> is never included.

Subject: [build] Remove obsolete HAVE_STDINT_H probing macro.
This macro was updated by the unix configure script and the
CMakeLists.txt one, but is never used in the source tree
(nor is <stdint.h> included anywhere), so removing it entirely
should be safe.
