CFLAGS ignored by python3/Makefile

[Дилян Палаузов]

I execute

export CFLAGS="-I/usr/local/include/python3.10" 
export LDFLAGS="-L/root/chroot-n/python/lib/"	 
./configure --with-python3 --prefix=/home/mailmanweb PYTHON3_LIB=/home/mailmanweb/lib/python3.10/site-packages 
cd python3 
make

The first command is:

depbase=`echo xapian_wrap.lo | sed 's|[^/]*$|.deps/&|;s|\.lo$||'`;\
/bin/sh ../libtool  --tag=CXX   --mode=compile g++ -DHAVE_CONFIG_H -I. -I..  -I/usr/local/include/python3.13  -fno-strict-aliasing -Wall -Wno-unused -Wno-uninitialized -fvisibility=hidden -fvisibility-inlines-hidden -I/usr/local/include -g -O2 -MT xapian_wrap.lo -MD -MP -MF $depbase.Tpo -c -o xapian_wrap.lo xapian_wrap.cc && mv -f $depbase.Tpo $depbase.Plo

so CFLAGS was ignored. Eventually I replaced in python3/Makefile and python3/.deps/xapian_wrap.Plo all 3.13 with 3.10
