2015-02-01Always pass 0 or option number to gfc_warning*.Joseph Myers
Similar to the issue with fatal_error that I fixed in <https://gcc.gnu.org/ml/gcc-patches/2015-01/msg02690.html>, the overloads of gfc_warning and gfc_warning_now (with and without a first argument for an option number) also break gcc.pot regeneration because xgettext expects the translated string argument to be in a fixed position for a given function name. This patch applies the corresponding fix of always passing a first argument (option number or 0), just like the core diagnostic functions warning and warning_at, and removing the problem overloads without it. Bootstrapped with no regressions on x86_64-unknown-linux-gnu. * error.c (gfc_warning (const char *, ...), gfc_warning_now (const char *, ...)): Remove functions. * gfortran.h (gfc_warning (const char *, ...), gfc_warning_now (const char *, ...)): Remove declarations. * arith.c, check.c, data.c, decl.c, frontend-passes.c, interface.c, intrinsic.c, io.c, matchexp.c, module.c, openmp.c, options.c, parse.c, primary.c, resolve.c, scanner.c, symbol.c, trans-common.c, trans-const.c, trans-stmt.c: All callers of gfc_warning and gfc_warning_now changed to pass 0 or option number as first argument.
