For those of us who don't read Chinese, Google Translate says that's

	Creating library libwireshark.lib and objects libwireshark.exp
	dissectors.lib (packet-ppp.obj): error LNK2019: unresolved external symbol _g_thread_init, the symbol is referenced in function _proto_register_ppp
	libwireshark.dll: fatal error LNK1120: 1 unresolved externals
	NMAKE: fatal error U1077: “"D:\Program Files\Microsoft Visual Studio 9.0\VC\BIN\link.EXE"”: return code "0x460"
	Stop.
	NMAKE: fatal error U1077: “"D:\Program Files\Microsoft Visual Studio 9.0\VC\BIN\nmake.exe"”: return code "0x2"
	Stop.

(why "fatal error" is in English and "return code" isn't, well...).

What happens if you *don't* make that change, but, instead, change epan\Makefile.nmake to do something such as

libwireshark_LIBS = \
	$(GTHREAD_LIBS)	\
	$(GLIB_LIBS)	\
	$(C_ARES_LIBS) \
	$(ADNS_LIBS) \
	$(KFW_LIBS) \
	$(NETTLE_LIBS) \
	$(ZLIB_LIBS) \
	$(GNUTLS_LIBS) \
	$(LUA_LIBS) \
	$(PYTHON_LIBS) \
	$(SMI_LIBS) \
	$(GEOIP_LIBS) \
	..\wsutil\libwsutil.lib \
	..\wiretap\wiretap-$(WTAP_VERSION).lib \
	crc\crc.lib \
	crypt\airpdcap.lib \
	ftypes\ftypes.lib \
	dfilter\dfilter.lib \
	$(WSLUA_LIB) \
	$(WSPYTHON_LIB) \
	dissectors\dissectors.lib

so that libwireshark is linked with $(GTHREAD_LIBS)?
