Subject: scanner.c (skip_free_comments): Return bool instead of void.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0d3abf6f9e44a3341754463170ff12d504e77530;p=gcc.git

scanner.c (skip_free_comments): Return bool instead of void.

	* scanner.c (skip_free_comments): Return bool instead of void.
	(gfc_next_char_literal): Don't return ' ' if & is missing after
	!$omp or !$.  Use skip_{free,fixed}_comments directly instead
	of gfc_skip_comments.
