[bug-myserver] MyServer 0.9.1 issues

[Ludovic Courtès]

Hello!

I tried to update the MyServer package for NixOS and stumbled upon these
issues.

First, ‘tests_suite’ (which should really be called ‘test_suite’) was
not explicitly linked against libgcrypt so something along these lines
was needed:

 tests_suite_LDADD = ../src/libmyserver.a  ../lib/libgnu.a $(CPPUNIT_LDFLAGS) \
        $(PTHREAD_LIB)  $(IDN_LIB) $(XNET_LIB) $(EVENT_LIB) $(DL_LIB) 
$(SSL_LIB) \
-       $(ZLIB_LIB) $(XML_LIBS) $(LDFLAGS)
+       $(ZLIB_LIB) $(XML_LIBS) -lgcrypt $(LDFLAGS)

Second, the test suite makes progress for some time and eventually
hangs, burning 100% CPU.  Attaching GDB at this point show this
(apparently this is all being compiled without debugging symbols):

Any idea?
