Subject: linc: FTBFS (amd64/gcc-4.0): static declaration of 'in6addr_any' follows non-static
 declaration

Package: linc
Severity: normal
Tags: patch

When building 'linc' on amd64 with gcc-4.0,
I get the following error:

 cc -DHAVE_CONFIG_H -I. -I. -I.. -I../include -I../include -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -Wall -Wunused -Wmissing-prototypes -Wmissing-declarations -DG_DISABLE_DEPRECATED -D_GNU_SOURCE -g -Wall -O2 -c linc-protocols.c -fPIC -DPIC -o .libs/linc-protocols.o

make[3]: *** [linc-protocols.lo] Error 1
make[3]: Leaving directory `/linc-1.0.3/src'

With the attached patch 'linc' can be compiled
on amd64 using gcc-4.0.
