(poplevel): If apparently nested inline function has
DECL_ABSTRACT_ORIGIN, don't output it; propagate TREE_ADDRESSABLE.
(pushdecl): When copying inline details into an extern decl,
copy DECL_RESULT, TREE_ASM_WRITTEN. Set DECL_ABSTRACT_ORIGIN.
From-SVN: r1781
But don't warn if function definition follows a declaration.
(pushdecl): Don't handle it here.
(grokparms): Don't warn about non-prototype decl in system header.
From-SVN: r1726
(duplicate_decls): Don't warn about disagreement in `inline'
except when non-inline fn is made inline after a call or definition.
(finish_function): Set BLOCK_SUPERCONTEXT of outer block.
From-SVN: r1449
(INSTALL): Deleted.
(duplicate_decls): If newdecl for builtin function
has same return mode as the builtin, keep the builtin
but use newdecl's return type.
From-SVN: r1366
(duplicate_decls): Never warn if redeclaring
a predeclared function. Use the new declaration's types
but keep any predeclared volatile flag.
From-SVN: r1227
