Update to 1.3.4
patch-aa were applied in upstream, so removed from here

Changes:
    20091220
	+ bump version to 1.3.4

	+ update INSTALL and README files.

	+ improve configure checks for math library.

	  + change test for NaN to use sqrt() rather than log() to work around
	    cygwin's partly broken math functions.

	  + add/use isnanf() to work around other breakage in cygwin math
	    functions.

	  + add configure check for _XOPEN_SOURCE, etc., needed to define
	    proper function pointer for sigaction, e.g., on Tru64.

	  + add check for sigaction function pointer, whose POSIX form is
	    absent from the cygwin header.

	+ extend MAWKBINMODE, adding a third bit which when set will suppress
	  the change for RS or ORS to use CR/LF rather than LF.  This is used
	  for MinGW to make the "check" rule in a build work, for instance.

	+ add configure check for functions used for pipe/system calls, e.g.,
	  for MinGW where these are absent.

	+ add runtime check for floating-point underflow exceptions

	+ fix an old 1.3.3 bug in re_split(), which did not check properly for
	  the end of buffer; this broke on Tru64.

	+ drop obsolete config-user, v7 and atarist subdirectories

	+ improve configure checks for sigaction, making the definitions used
	  in fpe_check.c consistent with matherr.c

	+ build fixes for AIX, Tru64.

	+ add configure check for 'environ'.

	+ remove redundant setlocale() calls; only LC_CTYPE and LC_NUMERIC
	  are used.

    20091213
	+ add makedeps.sh script to aid in updating object dependencies in
	  Makefile.in

	+ use "mkdir -p" rather than mkdirs.sh (suggested by Aleksey Cheusov).

	+ reformatted this file, to simplify extraction of contributor names.

	+ update config.guess and config.sub

	> patches by Jonathan Nieder:

	+ modify CF_DISABLE_ECHO autoconf macro to ensure that command lines
	  in Makefile.in begin with a tab.

	+ the makefile does not use $(MAKE); remove the SET_MAKE substitution.

	+ add some files to the "make clean" rule, in case make gets
	  interrupted in the middle of a rule.

	+ add a maintainer-clean rule to the makefile, to remove files which
	  could be regenerated.

	+ fix an unescaped "-" in man/mawk.1

	+ remove an unneeded cast in bi_funct.c

	+ fix an unused parameter warning in matherr.c

	+ drop unused line_no parameter from compile_error() and its callers.

	+ convert makescan.c to ANSI C, do further cleanup of that file.

	+ split-out scancode.h from scan.h
