Log message:
	Scheduler__DisableSwitching / Scheduler__EnableSwitching around wrappers
	
	I noticed calls to free() were missing some, and this
	whole area is both error-prone and almost completely untested:
	- it only matters when using user threads
	- and if thread switches occurs at just the right time
	
	This still leaves hazard in lots of custom wrappers.
	I suggest frontend handle this.
	
	allow NIL pointers in M3toC.Free*, silently do nothing with them
	(again here, we have VAR where CONST is really desired!)
	
	Upwd.c: use struct passwd and remove typedef struct passwd passwd_t
	I had generally done this, back end I discovered newer Solaris headers clash with such typedefs, alas
	
	Uin.c: add M3_DLL_EXPORT
