+hack	GCC2 isn't C99
+cdate	5 December 2003
+who	mrg
+file	gnu/dist/binutils/ld/ldlex.c: r1.2
+descr
+	ldlex.c is generated from ldlex.l and we get macro redefinition
+	errors from it if __STDC_VERSION__ is not C99 compliant.  This
+	hack forces NetBSD 1.6 and later systems to also include <stdint.h>
+	to get the relevant definitions.  This hack should be backed out
+	when all platforms have switched away from GCC2.
