On OS/390 during the run of Configure -des we see a problem on stderr:
Your select() operates on 32 bits at a time.
/bin/awk: Syntax error Context is:
>>> {print $} <<<
Generating a list of signal names and numbers...
the reason is that the cpp does not leave file names in its output on this
platform hence $fieldn is '' (and $pos is '???'). I've tried running:
awk "{print $}" some_text.file
on T62 Unix, AIX, HP-UX, Solaris, and dgux; and no vendor supplied awk can
handle that construct (admittedly I've not tried that with gawk on any
platform). Hence the following patch eliminates the use of awk altogether
in forming the initial signal list if $fieldn is blank. Sharp eyed Configure
hackers may note that the $fieldn value is used in the $awkprog in the
findhdr script, but on this platform all the headers that are found are
found with the initial -f test and the do loop in UU/findhdr never gets
executed here (but at least the stderr warnings are redirected in findhdr).
With this applied to a virgin _62 kit perl builds and tests OK on OS/390.
I've not tested this on any other platform, and I do not have a recent
dist kit to even patch that up - sorry :-{
