Hi,

Thanks for this concise summary.

This is already discussed in the top-level project README. You are the
first to complain about this.

https://sourceforge.net/projects/gawkextlib/files/

"Please download gawkextlib plus one or more individual extensions.  You should
build and install gawkextlib first."

In any case, it seems that not many people install these packages at all.
The hope is that a new front-end script may make it easier for people
to install and use, in which case the installation instructions will become
even less important.

For your definition of "wrong". As previously discussed, the hope is that
"gawkext" will do the right thing, so nobody will need to worry about
this issue unless they want to do development.

I don't understand this issue; the configure script should set GAWKPROG
as needed. The logic is in gawkext.m4:

AC_SUBST([GAWKPROG],"gawk${EXEEXT}")
AC_ARG_WITH(gawk,
        [AS_HELP_STRING([--with-gawk=PATH],[Use gawk in PATH])],
        [
                if test -d "$withval/lib"; then
                        LDFLAGS="-L${withval}/lib ${LDFLAGS}"
                else
                        LDFLAGS="-L${withval} ${LDFLAGS}"
                fi
                if test -d "$withval/include"; then
                        CPPFLAGS="-I${withval}/include ${CPPFLAGS}"
                else
                        CPPFLAGS="-I${withval} ${CPPFLAGS}"
                fi
                if test -x "$withval/gawk${EXEEXT}"; then
                        AC_SUBST([GAWKPROG],"$withval/gawk${EXEEXT}")
                elif test -x "$withval/bin/gawk${EXEEXT}"; then
                        AC_SUBST([GAWKPROG],"$withval/bin/gawk${EXEEXT}")
                elif test -x "$withval/usr/bin/gawk${EXEEXT}"; then
                        AC_SUBST([GAWKPROG],"$withval/usr/bin/gawk${EXEEXT}")
                fi
        ]
)

To test this, I just installed gawk from the master branch under prefix
/extra_disk/tmp/gawk-test. I then installed gawkextlib with this configure
command:

./configure --prefix=/tmp/gelib --with-gawk=/extra_disk/tmp/gawk-test

And then gawk-MPFR with this configure command:

./configure --prefix=/tmp/gelib --with-gawk=/extra_disk/tmp/gawk-test 
--with-gawkextlib=/tmp/gelib

Looking in <path to gawk-mpfr>/test/Makefile, I see this:

GAWKPROG = /extra_disk/tmp/gawk-test/bin/gawk

which is exactly as it should be. What's in your config.log file?
On my system:

bash-4.2$ grep GAWKPROG config.log
GAWKPROG='/extra_disk/tmp/gawk-test/bin/gawk'

Good.
