egcs-1.1 C++ parser bug fix for extern C

[Mumit Khan]

Please see http://www.cygnus.com/ml/egcs-bugs/1998-Sep/0180.html for my bug 
report to egcs-bugs.

The following patch fixes the following bug in the C++ parser (introduced
since egcs-1.0.3a when initdcl0_innards was added):
  
  === ext_c_bug1.cc
  extern "C" foo ();
  =================

  % gcc -c ext_c_bug1.cc
  ext_c_bug1.cc:1: warning: ANSI C++ forbids declaration `' with no type
  ext_c_bug1.cc:1: abstract declarator `int' used as declaration

This bug is causing a real headache thanks for lots of legacy C headers
that need to be maintained.

The parser stack in nomods_initdcl0 is setup incorrectly, and so when
initdcl0_innards calls parse_decl(), incorrect parameter is passed for
the declarator.

No testsuite regressions for i686-pc-linux-gnu and hppa1.1-hp-hpux10.20.

	* parse.y (nomods_initdcl0): Set up the parser stack correctly.
