+  * Cleanup: remove references to no longer used stdint.h
+  
+  Since 19c50b9d (Unconditionally use inttypes.h instead of trying for stdint.h
+  (simplification) and remove the now unnecessary inclusion in
+  pcre2_internal.h., 2018-11-14), stdint.h is no longer used.
+  
+  Remove checks for it in autotools and CMake and document better the expected
+  build failures for systems that might have stdint.h (C99) and not inttypes.h
+  (from POSIX), like old Windows.
+  
+  * Cleanup: remove detection for inttypes.h which is a hard dependency
+  
+  CMake checks for standard headers are not meant to be used for hard
+  dependencies, so will prevent a possible fallback to work.
+  
+  Alternatively, the header could be checked to make the configuration fail
+  instead of breaking the build, but that was punted, as it was missing anyway
+  from autotools.
