+Subject: [PATCH] trousers: resolve build failure
+
+The global variables tcsd_sa_chld and tcsd_sa_int in tcsd.h are
+causing build failures in latest Fedora release:
+
+/usr/bin/ld: ../../src/tcs/libtcs.a(libtcs_a-tcsi_changeauth.o):/builddir/build/BUILD/trousers-0.3.13/src/tcs/../include/tcsd.h:169: multiple definition of `tcsd_sa_chld'; tcsd-svrside.o:/builddir/build/BUILD/trousers-0.3.13/src/tcsd/../../src/include/tcsd.h:169: first defined here
+/usr/bin/ld: ../../src/tcs/libtcs.a(libtcs_a-tcsi_changeauth.o):/builddir/build/BUILD/trousers-0.3.13/src/tcs/../include/tcsd.h:168: multiple definition of `tcsd_sa_int'; tcsd-svrside.o:/builddir/build/BUILD/trousers-0.3.13/src/tcsd/../../src/include/tcsd.h:168: first defined here
+
+They are no longer used since 9b40e581470b ("Improved daemon's signal
+handling") so just remove them.
