Re: [patch/rfc/testsuite] Add "compiler_info"

[mec.gnu@mindspring.com (Michael Elizabeth Chastain)]

Proofread and tested, no problems.  I'm appending a little snippet
of test code.  I tested with:

  gcc 2.95.3		# reports gnuc-2-95
  gcc 3.2-7-rh		# reports gnuc-3-2
  gcc 3.3.2		# reports gnuc-3-3
  gcc gcc-3_3-branch	# reports gnuc-3-3
  gcc HEAD		# reports gnuc-3-4

I didn't test the non-gcc path.

I prefer "gcc" to "gnuc" but "gnuc" is okay by me.

Recommended for approval.
