attached, although it is not ready for check-in.

On Fedora 21 x86_64 it builds now 32-bit target with mingw-w64, you are right
that with the 'compile' patches I checked in it did not.

But mingw-w64 64-bit target would build OK (after commenting out the mkdtemp()
call) before adding the gnulib mkdtemp module.  But after the gnulib mkdtemp
addition there are many errors (attached as the second attachment).  It is all
about
	struct timeval *
vs.
	struct rpl_timeval *
but an advice from mingw64 aware hacker would be nice to know what to do.


Thanks,
Jan

Hi Jan,
I can reproduce your build failure with x86_64-w64-mingw32-gcc too.
Looks gnulib sys_time module needs update, or maybe we have to use win32
api, such as GetTempPath and GetRandomFileName.

Do you mean that the problem is solved with a more recent version
of gnulib?

I would personally take a two-step approach: First, immediately
fix the build issue using the second recommendation you made, which
is to use win32 routines on Windows hosts for now.  Then, we can
work towards first upgrading gnulib, and then importing mkdtemp.
I find that updating gnulib to always be fairly disruptive, which
is why I propose we stabilize the problem first to get builds
working back ASAP, and then look at gnulib.

No, that isn't what I meant.  What I mean by "update" is to fix the
problem in gnulib sys_time and update gnulib import.  Sorry for the confusion.

Does it mean that after upgrading gnulib we can drop the MS-Windows host
routines (which need to be written yet) again?

IMO a more clean solution would be s/gdb_select/select/g, drop gdb_select from
mingw-hdep.c and import gnulib select instead which handles what gdb_select is
there fore, hopefully more transparently.  But I haven't tried any of that.

Beware: each such replacement must be carefully studied before
concluding that it is what we want.  In particular, Gnulib's 'select'
is a "package deal": when you import it, you get more than what you
asked for.  Some potential issues are with blocking/non-blocking
sockets and anonymous pipes.

IOW, it's not an easy decision, at least not with 'select'.

Provided that the corresponding gnulib modules can in fact be
imported without problem, then my answer would be yes. As you
found out, it often does not work that way. So far, if you look
at your update, and yao's update not so long ago, it's 3 breakages
(I found 2, you found 1).  gnulib provides a really nice abstraction
layer, but it does not always work the way we hoped!

As Eli pointed out, it's not necessarily an easy change. I don't
see the relation between select and mkdtemp, but maybe I missed
something.

Could someone write the MS-Windows calling code.  I can try that myself but I
cannot test it much, from what I tried in the past gdb.exe does not work much
under Wine.

OK.

Importing mkdtemp from gnulib broke select() calls:

If you write it, I can test it.

Or I can write it myself, but then it will take a few days.
