In usr.bin/make/var.c, function ParseModifier(), initialize the 'error'
variable to NULL, to avoid using it uninitialized in certain cases. This fixes the following clang 3.2 warning: usr.bin/make/var.c:1770:10: error: variable 'error' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized] if (vp->execute) { ^~~~~~~~~~~ usr.bin/make/var.c:1777:10: note: uninitialized use occurs here if (error) ^~~~~ usr.bin/make/var.c:1770:6: note: remove the 'if' if its condition is always true if (vp->execute) { ^~~~~~~~~~~~~~~~~ usr.bin/make/var.c:1768:23: note: initialize the variable 'error' to silence this warning const char *error; ^ = NULL MFC after: 1 week
