The behavior in escaping '#' in strings has changed in 4.3 and above.
When using Make 4.3 (Ubuntu 22 LTS) or 4.4 (also U22, built from src) to
compile gstreamer 1.16.2, compile fails due to differences in how macros with
# are expanded.
libs/gst/controller/Makefile.in:595
enum_headers = $(foreach h,$(glib_enum_headers),\n\#include \"$(h)\")
In the expanded enum_headers, make 4.3+ will now include an extra \ in front
of the #, while 4.2.1 will use that \ to escape the #.
