Argh. As one door opens, another slams viciously shut in my face. For some
reason autoconf has gone over to the dark side:
configure:1616: checking for i686-pc-cygwin-gcc
configure:1642: result: cl
configure:1926: checking for C compiler version
configure:1929: cl --version </dev/null >&5

LOLWUT? It turns out something has gone horribly wrong in the alternatives
department now:
$ gcc
bash: gcc: command not found
$ gcc.exe
bash: gcc.exe: command not found
$ file /bin/gcc.exe
/bin/gcc.exe: broken symbolic link to `/etc/alternatives/gcc'
$ ls /etc/alternatives/gcc -la
lrwxrwxrwx 1 DKAdmin None 3 Apr 6 04:29 /etc/alternatives/gcc -> ??/
$ /usr/sbin/alternatives.exe --help
$ echo $?
128
$
And, right; alternatives.exe needs the ctype_ptr import. And I'll bet that
p7zip doesn't use any ctype functions. It looks like if you want to revert
back across the change, you need to revert any/all of these as well:
cygwin
m4
alternatives
diffstat
vim
xxd
and that may not be a complete list. Rolling back alternatives appeared to
fix everything but I went and re-ran the --config option anyway.
I wonder if m4 suddenly changed its behaviour as a result of now being
locale sensitive, which had knock-on effects on autoconf and bison, which
causes the trouble by doing something unexpected when generating the ld or ar
parsers.. I don't have any of LANG or LC_* set in my environment so I thought
I ought to just have the standard C locale, but I don't understand it well.
cheers,
