[RFC] solib-svr4.c gdb_byteised.

[Manoj Iyer <manjo@austin.ibm.com>]

solib-svr4.c compiles without errors on ppc64 with gcc4.0. Here is a
patch...


2005-05-26  Manoj Iyer  <manjo@austin.ibm.com>

	* solib-svr4.c: lm_info structure convert type of lm to gdb_byte.
	(elf_locate_base): Converted types of buf, bufend, pbuf, to gdb_byte.
	(first_link_map_member): Converted type of r_map_buf to gdb_byte.
	(open_symbol_file_object): Converted type of l_name_buf to gdb_byte.
	(svr4_fetch_objfile_link_map): Converted type of l_name_buf to
	gdb_byte.
