+Specifies the value to be assigned to @code{finalize_syms} before the function
+@code{size_segs} is called. Since @code{size_segs} calls @code{cvt_frag_to_fill}
+which can call @code{md_convert_frag}, this constant governs whether the symbols
+accessed in @code{md_convert_frag} will be fully resolved. In particular it
+governs whether local symbols will have been resolved, and had their frag
+information removed. Depending upon the processing performed by
+@code{md_convert_frag} the frag information may or may not be necessary, as may
+the resolved values of the symbols. The default value is 1.
