Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.

/* Use the bsd assembler syntax. */
/* 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.
