Hi Rolf,

Sorry for dropping out on you.

I checked that gdbserver now builds OK with the attached patch
on mingw32 and linux.

Daniel, OK to check in?

	* configure.ac: Check for memmem declaration.
	* server.c [HAVE_MALLOC_H]: Include malloc.h.
	(disable_packet_vCont, disable_packet_Tthread, disable_packet_qC)
	(disable_packet_qfThreadInfo): Unconditionally compile.
	* server.h [!HAVE_DECL_MEMMEM]: Declare memmem.
	* configure, config.in: Regenerate.
