php81-apache2handler @8.1.28_0 fails to build against current libxml2

[murrayE]

During configure, I see in Terminal error:

Warning: Configuration logfiles contain indications of -Wimplicit-function-declaration; check that features were not accidentally disabled:
  _controlfp_s: found in php-8.1.28/config.log
  _controlfp: found in php-8.1.28/config.log
  gethostbyname_r: found in php-8.1.28/config.log

From main.log file, during build:
