Hi,
With postfix-3.8-20230314:
clang -fPIC -I. -I../../include -DHAS_PCRE=2 -DUSE_TLS -DHAS_LMDB -DNO_NIS
-DNO_DB -DDEF_DB_TYPE=\"lmdb\" -DHAS_CDB -I/usr/include/cdb -DHAS_DEV_URANDOM

-DUSE_DYNAMIC_LIBS -UUSE_DYNAMIC_MAPS -Wmissing-prototypes -Wformat
-Wno-comment -fno-common -O2 -march=native -I. -I../../include -DLINUX6 -c
smtp_proto.c
I am getting
smtp_proto.c:1200:39: warning: implicit truncation from 'int' to a one-bit wide
bit-field changes value from 1 to -1
[-Wsingle-bit-bitfield-constant-conversion]
state->logged_line_length_limit = 1;
^ ~
1 warning generated.
It is nit in the sense that it is still not zero and hence no change in
behaviour. GCC gives a similar warning with -Wpedantic. Still, it might
be a good idea to change logged_line_length_limit from int to unsigned.
