Subject: [PATCH] Fix building with GCC 10
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GCC 10 defaults to -fno-common option resulting in a linker error like
this:

gcc -o speedy_backend speedy_backend_main.o speedy_perl.o speedy_util.o speedy_sig.o speedy_frontend.o speedy_backend.o speedy_file.o speedy_slot.o speedy_poll.o speedy_ipc.o speedy_group.o speedy_script.o speedy_opt.o speedy_optdefs.o xsinit.o  -Wl,--enable-new-dtags -Wl,-z,relro -Wl,--as-needed -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-z,relro -Wl,--as-needed -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -fstack-protector-strong -L/usr/local/lib  -L/usr/lib64/perl5/CORE -lperl -lpthread -lresolv -ldl -lm -lcrypt -lutil -lc
/usr/bin/ld: speedy_perl.o: in function `$d':
/builddir/build/BUILD/CGI-SpeedyCGI-2.22/speedy_backend/../src/speedy_perl.h:24: multiple definition of `my_perl'; speedy_backend_main.o:/builddir/build/BUILD/CGI-SpeedyCGI-2.22/speedy_backend/../src/speedy_perl.h:24: first defined here

This commit corrects the my_perl declaration to be indeed
a declaration and not a definition.
