Hi,
We have just released 7.6.6 of the v7-stable branch.
I've got a build error in 7.6.6:

lexer.l:34: error: conflicting types for 'strdup'
make[4]: *** [libgrammar_la-lexer.lo] Error 1
make[4]: Leaving directory `/usr/src/rsyslog-7.6.6/grammar'
offending line seems line 1462 in lexer.c:
extern char *strdup(char*); /* somehow we do not get this from
string.h... */
If I drop that line build is OK.
My string.h does have strdup, but defined as: extern char
*strdup(__const char*);
Following patch also works:
diff --git a/grammar/lexer.l b/grammar/lexer.l
index 796815c..4da4b8d 100644
--- a/grammar/lexer.l

string.h... */
%}
%option noyywrap nodefault case-insensitive yylineno
But I do not know if that matches all variants of strdup that may be out
there.
FWIW 7.6.3 builds OK, have not tried 7.6.4/5
