Subject: * gcc/pretty-print.c (eat_esc_sequence): Swap the foreground and background
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6461f5a2e10fa5983e8467d3f4f0b9374c1aea36;p=thirdparty%2Fgcc.git

* gcc/pretty-print.c (eat_esc_sequence): Swap the foreground and background
colors if the COMMON_LVB_REVERSE_VIDEO flag is set, and clear it thereafter,
as it only works for DBCS.
