Iglesias" Date: Mon, 19 Apr 2010 22:36:02 +0200 From: Thomas Monjalon Using GCC-4.2.4-1ubuntu4, there is a warning: microblaze-dis.c:792: warning: unused variable 'fprintf' Indeed, fprintf() is shadowed by a custom redefinition but is not used because of FORTIFY_SOURCE option which replace calls to fprintf() by fprintf_chk(). It is fixed by renaming the variable which prevents from hazardous shadowing.
