Subject: Merge STR and VG__STRING macros into one, VG_STRINGIFY.  Also, in
X-Git-Tag: svn/VALGRIND_3_0_0~864
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e2e1d2f896002fc3393ea6dcebab797c2910fc69;p=thirdparty%2Fvalgrind.git

Merge STR and VG__STRING macros into one, VG_STRINGIFY.  Also, in
valgrind-listener.c, don't use the VG_ prefix on its equivalent, because
it's a local definition.
