688	TCP unit tests broke ia64 build	Jakub Jermář	Jiri Svoboda	"The CI tests [http://ci.helenos.org/build-35/logs/helenos-build-ia64-ski.log discovered] a breakage of the ia64 build. A closer look reveals that the introduction of the TCP unit tests broke the build on all platforms that don't use `--gc-sections` during linking. This currently includes only ia64 and abs32le. The build of the `tcp` service ends with the follow error:

The missing symbol `tcp_transmit_pdu` is defined in tcp.c. However, adding this file to the test sources is problematic because it also defines `main`, which would become duplicit for the test."	defect	closed	major	0.7.1	helenos/net/tcp	mainline	fixed	ia64, tcp
