Handles relocation or line-number field overflows in an XCOFF32 file. (XCOFF64 files may not have overflow section headers.) If a section has more than 65,534 relocation entries or line number entries, both of these fields are set to a value of 65535. In this case, an overflow section header with the s_flags field equal to STYP_OVRFLO is used to contain the relocation and line-number count information.
