Subject: 	* parser-defs.h: Add "extern" to start of variable declarations so
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7944822188eb0d050112f2de13d0c7513692a042;p=binutils-gdb.git

	* parser-defs.h: Add "extern" to start of variable declarations so
	we don't end up with commons.
	* parse.c: Define these variables.
