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.
