cpphash.h (IN_I): New flag for directive table.
* cpphash.h (IN_I): New flag for directive table.
* cpplib.c (DIRECTIVE_TABLE): Mark #define, #undef, #ident, and
#pragma with IN_I.
(_cpp_check_directive): If -fpreprocessed, execute directives
marked with IN_I. Issue no warnings in this case.
* cpplex.c (_cpp_get_token): Expand no macros if -fpreprocessed.
