CFLAGS -- were: CFLAGS = -I/opt/include -I/opt/buildaix/include -O2 
-DNDEBUG -D_XOPEN_SOURCE_EXTENDED=1 -DGAWK_AIX=1

now
CFLAGS = -I/opt/include -I/opt/buildaix/include -g -DNDEBUG 
-D_XOPEN_SOURCE_EXTENDED=1 -DGAWK_AIX=1

head from config.log...
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by GNU Awk configure 4.1.3, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure --prefix=/opt --sysconfdir=/var/gawk/etc 
--sharedstatedir=/var/gawk/com --localstatedir=/var/gawk 
--mandir=/usr/share/man --infodir=/opt/share/info/gawk

Well, 98%...

Make check passes the previous full stop:
...
synerr1
synerr2
tradanch
tweakfld
uninit2
uninit3
uninit4
...
But just "goes to sleep", i,e., the system is idle, but this is what I 
see as output:

...
printfbad1
printfbad2
printfbad3
printfbad4
printhuge
procinfs
profile0
profile1
profile2
profile3
profile4
profile5
profile6
profile7
pty1

a) you are probably correct that it is a compiler error - just wish I 
was smart enough to debug that.
b) I do not have gdb and I am seven left thumbs when it comes to the AIX 
debugger (dbx I believe), although kdb can supposedly look at things 
post-mortum. Also too little experience.

Many thanks to you!
p.s. I am taking a vacation - no computers (not even a smart phone), so 
my next reply will be a few weeks.
