%CC-W-MIXLINKAGE, In this declaration, "vms_show" is declared with both internal and external linkage. The previous declaration is
at line number 33 in file DISK$USER1:[TGRACE.CURL.CURL-7_29_0.SRC]TOOL_VMS.H;1.

%LIBRAR-W-COMCOD, compilation warnings in module TOOL_MAIN file DISK$USER1:[TGRACE.CURL.CURL-7_29_0.PACKAGES.VMS.ALPHA]TOOL_MAIN.OBJ

I have fixed this with, below,,, also linker needed a symbol def as neither of the "extern vms_show" were providing it. This may be due to our default mode of the compile mode of "extern" since there are several options for this.

$ diff tool_main.c ;1
