bug#15681: automake 1.14, make check failures on AIX

[Thomas Jahns]

Hello,

I've built automake 1.14 on our AIX 6.1 system, there are some bugs creeping up.
Two (libtool7 and libtool9) are more of a libtool affair which I've filed
separately to the libtool bug list.

The others are problems with automake itself it seems.

Those which were related to t/get-sysconf.sh I already fixed.

Please find the attached patch which handles a problem with the attempt to call
lex with option --version.
AIX lex gives the following behaviour when called as lex --version:

$ lex --version
0: Warning: 1285-300 The - flag is not valid.
0: Warning: 1285-300 The e flag is not valid.
0: Warning: 1285-339 Ratfor is not supported with lex.
0: Warning: 1285-300 The s flag is not valid.
0: Warning: 1285-300 The i flag is not valid.
0: Warning: 1285-300 The o flag is not valid.

At this point the program hangs waiting for input on stdin.

When entering C-D and line-feed, lex finished:

^D
Error: 1285-340 The rules section delimiter is missing.
$

The one in t/lex-clean-cxx results from mainfoo.cc not correctly declaring yylex
as extern "C". I therefore propose to change the declaration in mainfoo.cc
accordingly. Please see the attached patch.

Unfortunately I don't understand what's tripping up t/lex-line, but I'm quite
willing to test any suggestion.

The same is true for t/tap-signal-w. No idea what's going on there.

Regards, Thomas
