[Bug bootstrap/21512] New: build failure on ppc-apple-darwin5.5 in libcpp

["fxcoudert at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

When compiling libcpp/init.c:
../../gcc/libcpp/init.c:59: parse error before `,'
[9 times]

This error happens on:

TRIGRAPH_MAP
  s('=', '#')   s(')', ']')     s('!', '|')
  s('(', '[')   s('\'', '^')    s('>', '}')
  s('/', '\\')  s('<', '{')     s('-', '~')
END

which, once preprocessed, is:

__extension__ const uchar _cpp_trigraph_map[255  + 1] = {
  [ '=' ] =   '#' ,     [ ')' ] =   ']' ,       [ '!' ] =   '|' ,
  [ '(' ] =   '[' ,     [ '\'' ] =   '^' ,      [ '>' ] =   '}' ,
  [ '/' ] =   '\\' ,    [ '<' ] =   '{' ,       [ '-' ] =   '~' ,
};

The following minimal code:

__extension__ const unsigned char _cpp_trigraph_map[255  + 1] = {
  [ '=' ] =   '#' ,     [ ')' ] =   ']' ,       [ '!' ] =   '|' 
};

compiles fine on my linux box but gives 3 "parse error before `,'" on ppc-darwin5.5.

A workaround seems to specify -DHAVE_DESIGNATED_INITIALIZERS=0.
