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

[fxcoudert at gcc dot gnu dot 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.

This is caused by moving libcpp to the toplevel.

This is a bootstrap bug, the bug is in the toplevel Makefile.

Tried again to build gcc on powerpc-apple-darwin5.5 (MacOS 10.1), with the
workaround for the bug reported in comment #0.

Fails with error message:
../../gcc/gcc/config/rs6000/host-darwin.c:25: sys/ucontext.h: No such file or
directory

System header sys/ucontext.h appeared with MacOS 10.2. Something intelligent
should be done for systems without sys/ucontext.h.

That is a host bug and should be filed separately.

Will be fixed by toplevel bootstrap.

targetting torwards 4.2 since 4.1 will not have top level bootstrap enabled by default.

So, if I understand correctly, you're meaning that gcc 4.0 and 4.1 will not
build on ppc-apple-darwin5.5? I find that a litlle... disappointing.

Well the work around is to use 3.4 to build 4.0, that will fix the bug reported here but not the sys/
ucontext.h bug which should have been reported seperately and is a bug in config/darwin.h.
