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 and as a result raises an arror when
linking nasd:

gcc -o nasd -O2 -fno-strict-aliasing   -Wl,-z,relro -Wl,--as-needed  -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld  -L../lib/audio -L/usr/lib64 -L/usr/lib64    dia/libdia.a dda/voxware/libvoxware.a os/libos.a
/usr/bin/ld: dia/libdia.a(lex.o): in function `$d':
lex.c:(.bss+0x48): multiple definition of `yyin'; dia/libdia.a(main.o):/builddir/build/BUILD/nas-1.9.4/server/dia/main.c:79: first defined here
collect2: error: ld returned 1 exit status

The reason is that both lex.c (generated from lex.l) and main.c
define yyin global variable.

This patch changes the main.c definition into a declaration.
