+/* we need to do this because gas is really a bsd style assembler,
+ * and so doesn't work well this these att-isms:
+ *
+ *  ASM_OUTPUT_SKIP is .set .,.+N, which isn't implemented in gas
+ *  ASM_OUTPUT_LOCAL is done with .set .,.+N, but that can't be
+ *   used to define bss static space
+ *
+ * Next is the question of whether to uses underscores.  RMS didn't
+ * like this idea at first, but since it is now obvious that we
+ * need this separate tm file for use with gas, at least to get
+ * dbx debugging info, I think we should also switch to underscores.
+ * We can keep i386v for real att style output, and the few
+ * people who want both form will have to compile twice.
