Feedback for BETA release of GNU Awk 5.1.1.f

Feedback for BETA release of GNU Awk 5.1.1.f Cygwin Install under Windows
10 Pro

This was *my first build* of Gawk from source and the result looks to be
excellent. I experienced a few bumps along the road doing this first
install, configure, and make.

Following the instruction in B.3.1.4 Using gawk In The Cygwin Environment
**** Doc note:* change gawk-5.1.0.tar.gz to *gawk-5.1.1.tar.gz*  *** very
minor detail

My first ./configure had some messages about missing libraries

**** Needed to install the following packages to Cygwin via
setup-x86_64.exe *(non-defaults for Cygwin, but *required for a full Gawk
make*). I simply checked them off the Cygwin gui install list:

autoconf package (wrapper, I assumed it was needed)
autoconf2.5 package (== latest version)
bison
byacc
ELFIO package
gmp library
libsigsegv library
libiconv2 library
mpfr library
texinfo
------------
*** very minor: consider changing ("checking for ELF binary format;
result=no") to "checking for *ELFIO* binary format" in both
\gawk5.1.1\*configure
*[lines 8387-88] and \gawk5.1\*extension\configure* [lines 6245-46]
Why: makes it easier to find "ELFIO" in the Cygwin package list.

Lastly, I didn't know I would have to *manually *build the PDF doc. IF easy
to add to the make, might be user friendly to newbies like me *and/or* add
one line to the   B.3.1.4 Using gawk In The Cygwin Environment page.

$ *../bin/texi2pdf  doc/gawk.texi *-output=gawk5.1.1f.pdf (personal quirk
keep some filenames unique)

So far, everything looks great running gawk programs. I have some test
explorations of Gawk that I have been doing for the past 6 months, so I'll
do a re-stress test with them and let you know if anything pops up that is
more interesting than my install feedback. Thank you and all the very best
to all of you who made this beta happen!!! -John Naman
