This is definitely a configure problem. If mkdtemp function was found
(and it was because HAVE_MKDTEMP was set to 1) then it should find
mkdtemp in the headers.

I don't know, possibly they moved the header file in which mkdtemp is
defined in your new version of Cygwin.

That all sounds right to me. Must be the "new" version of Cygwin. Go
to /usr/include and do this:

find . -name '*.h' -exec grep mkdtemp {} \; -print

and let me know if you get any output. The output will tell you which
header file mkdtemp is defined in. Make sure that is the header that is
included in lib/System/Unix/Path.inc (it might be a few #includes
removed).

That would be bad for this entire process. How is it failing? Any output
from it?

That's all just bizarre but its possible that it is related to a more
fundamental error, especially a configure script problem.

Hrm. That's not good. 

Can you build with "TOOL_VERBOSE=1" and capture the output and send it
to me. Something like:

make TOOL_VERBOSE=1 2>&1 >make.out

Send that to me (not the list) and I'll take a look. Please also do
this:

make reconfigure

and send me the "configure.out" file that gets generated as well as
"config.log".

Yeah, as I suspected, its probably related to the new version of Cygwin.

There's something fishier than just your inst >>>A<<< ll :) procedure at
work here.
