The title says it all.  Tested on hppa2.0w-hp-hpux11.11 with gcc 3.4.4
and 4.0.0 with no regressions in the testsuite.  Committed to trunk.

	* som.c (try_prev_fixup): Changed type of subspace_reloc_sizep to
	unsigned int *.
	(som_write_space_strings): Change type of tmp_space and p to char *.
	(som_write_symbol_strings): Likewise.  Also change type of comp to
	char *comp[4].
	(som_begin_writing): Change type of strings_size to unsigned int.
	(som_finish_writing): Likewise.
	(som_slurp_reloc_table): Change type of external_relocs to unsigned
	char *.
	* som.h (struct som_section_data_struct): Change type of reloc_stream
	field to unsigned char *.
