hex.c (_hex_value): Make this unsigned.

libiberty/ChangeLog:
2003-05-14  Jim Blandy  <jimb@redhat.com>

	* hex.c (_hex_value): Make this unsigned.
	(hex_value): Update documentation for new return type.  hex_value
	now expands to an unsigned int expression, to avoid unexpected
	sign extension when we store it in a bfd_vma, which is larger than
	int on some platforms.
	* functions.texi: Regenerated.

include/ChangeLog:
2003-05-14  Jim Blandy  <jimb@redhat.com>

	* libiberty.h (hex_value): Make the value an unsigned int, to
	avoid unexpected sign-extension when cast to unsigned types larger
	than int --- like bfd_vma, on some platforms.
	(_hex_value): Update declaration.
