Hi
Attempting to build xscreensaver using using gcc 10.4
$ CFLAGS="-Wimplicit-function-declaration -Wnested-externs" ./configure
--prefix=/opt/xscreensaver
Everything is fine until
gcc -D__EXTENSIONS__ -std=gnu99 -pedantic -Wall -Wnested-externs
-Wstrict-prototypes -Wmissing-prototypes -Wno-overlength-strings -c -I.
