#21 compilation error by using gcc v15.1 : error: too many arguments to function 'auth_method->release_authentication_header'; expected 0, have 1

[Tyrone S.]

When i try to compile c-icap by using the now default gcc v15.1 on my gentoo box i run into the error

x86_64-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I.    -fvisibility=hidden -I./include/ -I./include/ -DCONFDIR=\"/etc/c-icap\" -DMODSDIR=\"/usr/lib64/c_icap/\" -DSERVDIR=\"/usr/lib64/c_icap/\" -DLOGDIR=\"/var/lib/log/\" -DDATADIR=\"/usr/share/c_icap/\"  -D_REENTRANT -march=native -O2 -pipe -Wall -D_FILE_OFFSET_BITS=64 -c -o c_icap-http_auth.o `test -f 'http_auth.c' || echo './'`http_auth.c

This i very likely a result of switching to -std=gnu23/-std=c23 by default which implies the removal of support for unprototyped functions. He're some hints and suggestions to deal with the issue: https://wiki.gentoo.org/wiki/Modern_C_porting#Fixes_.28C23.29

Please let me know if there's anything that i can do.

Thanks & best regards,
