I have just re-installed Autoconf v2.50 without GAWK on the PATH and no 
AWK variable set. When attempting to build SED, autoconf complains with:-

autoconf.[753]: gawk: not found

I'm not not hot when it comes to shell scripts, but this where AWK 
seems to be evaluated:- 

 
# Variables.
: ${autoconf_dir=${AC_MACRODIR=u:/usr/local/share/autoconf}}
test -z "$AC_ACLOCALDIR" &&
  AC_ACLOCALDIR=`(aclocal --print-ac-dir) 2>/dev/null`
: ${AWK=gawk}
debug=false
