Subject: Remove EXTERN from buildsym.h
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b80a981d0867f554d382eef9fc16081b12ac0543;p=binutils-gdb.git

Remove EXTERN from buildsym.h

Nothing in buildsym.h relies on the "EXTERN" method of
declaration/definition, so remove the traces.

2018-07-20  Tom Tromey  <tom@tromey.com>

	* buildsym.h (EXTERN): Don't define or undef.
	* buildsym.c (EXTERN): Don't define.
