Yes, I really miss it:

configure:8679: checking for __cxa_demangle in -lstdc++
configure:8702: gcc -o conftest -O2 -Wall -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=3
-fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables
-fstack-clash-protection -Werror=return-type -flto=auto -ffat-lto-objects
-Werror=date-time -g  -flto=auto -ffat-lto-objects conftest.c -lstdc++   >&5
/usr/lib64/gcc/x86_64-suse-linux/13/../../../../x86_64-suse-linux/bin/ld:
cannot find -lstdc++: No such file or directory
collect2: error: ld returned 1 exit status
configure:8702: $? = 1
