Subject: [PATCH] * cppexp.c (cpp_interpret_integer): Don't force
traditional numbers to be unsigned. * cpplib.c
(prepare_directive_trad): Set line number for diagnostics. * cpptrad.c
(scan_out_logical_line): Continue scanning out at start of buffer.
* gcc.c (trad_capable_cpp): Use cc1 always. f: * lang-specs.h: Use
cc1 for traditional preprocessing. testsuite: * gcc.dg/cpp/assert_trad1.c,
gcc.dg/cpp/assert_trad2.c, gcc.dg/cpp/assert_trad3.c,
gcc.dg/cpp/defined_trad.c, gcc.dg/cpp/hash2.c, gcc.dg/cpp/tr-define.c,
gcc.dg/cpp/tr-direct.c, gcc.dg/cpp/tr-sign.c, gcc.dg/cpp/tr-str.c,
gcc.dg/cpp/uchar-2.c: Remove.
