+Subject: [PATCH] Convert holler and bail to variadic function
+
+Both functions usually consume different types than char * which is
+problematic for some compliers like clang-16 where -Werror=implicit-int
+is enabled by default.
+
+The fix is done in such a way that original holler function is converted
+to vholer which uses va_list from stdarg.h and holler and bail are
+converted to variadic functions that utilize vholler for printing.
+
+Bug: https://bugs.gentoo.org/871003
