1999-10-22 Nick Clifton <nickc@cygnus.com>
* dlltool.c (struct mac): Add new field 'how_default_as_switches'.
(mtable): Initialise new field. Some machines have a non empty
string for this field.
(HOW_BFD_TARGET): Undefine and replace with...
(HOW_BFD_READ_TARGET): New macro: bfd target to use when opening a
file for reading. This is set to 0 so that any recognisable bfd
format can be read.
(HOW_BFD_WRITE_TARGET): New macro: bfd target to use when opening
a file for writing. This is set to the target machine type.
(ASM_SWITCHES): New macro: default switches to use when assembling
a file.
(assemble_file): New function: Assemble a source file into a
destination object file.
(gen_exp_file): Use assemble_file to create the exp file.
(make_one_lib_file): Use assemble_file to create the lib file.
Open output file use HOW_BFD_WRITE_TARGET and input files using
HOW_BFD_READ_TARGET.
(make_head): Use assemble_file to create the head file.
(make_tail): Use assemble_file to create the tail file.
(gen_lib_file): Open output file use HOW_BFD_WRITE_TARGET.

* ar.c (normalize): Fix full_pathname code.
