[PATCH]: Fix -Wc++-compat for alpha-dec-vms and i386-unknown-netware

[Kaveh R. GHAZI]

Testing some of the more unusual targets revealed a couple of more warning
nits which I fixed below.

Tested via "make cc1 xgcc" in cross-config to alpha-dec-vms and
i386-unknown-netware (among others).

Okay for mainline?

		Thanks,

	* config/alpha/alpha.c (alpha_need_linkage, alpha_use_linkage):
	Fix -Wc++-compat and/or -Wcast-qual warnings.
	* config/i386/netware.c (gen_stdcall_or_fastcall_decoration,
	gen_regparm_prefix): Likewise.
	* vmsdbgout.c (write_modbeg, lookup_filename,
	vmsdbgout_source_line, vmsdbgout_init): Likewise.
