Subject: 	* symbols.c(colon): if a symbol is being multiply defined as exactly
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=159fbb6088f17a341bcaaac960623cab881b4981;p=binutils-gdb.git

	* symbols.c(colon): if a symbol is being multiply defined as exactly
	the same value, then don't cause a fatal error. This fixes
	P00000616 - where a def _foo= . followed by foo: is seen.
