Hi Emacs,
I'm having issues building Emacs after a recent update. I'm now getting:
/home/matthew/.emacs_imp/src/xfns.c:4322: undefined reference to `x_get_net_workarea'
When I revert the revision: eggert@cs.ucla.edu-20130507053401-0nu6s4p8gb1fvsx0
this fixes the problem.
Thanks,
Matt

One would hope people would at least compile before checking in, but apparently not.
Trunk is fixed now.

Sorry about that; but I did compile, and it worked on my platform.
Unfortunately I didn't notice one of the ifdefs that didn't trigger
for my platform. I checked in a further version that should work
for both kinds of platforms.

#if !defined USE_GTK || GTK_MAJOR_VERSION < 3 + (GTK_MINOR_VERSION < 4)
This will be true for Gtk 4.0 to 4.3, 5.0 to 5.3, 6.0 to 6.3 and so on, so it is obviously not correct.

Sorry, I don't see the bug. Perhaps you misread the "+" as "|"?
For 4.0, for example, GTK_MAJOR_VERSION is 4 and GTK_MINOR_VERSION is 0,
so the comparison evaluates to 4 < 3 + (0 < 4),
which is false, which is what is wanted here.

I mixed up the precedence of < and +. Anyway, this is more unclear that the corresponding #if later in the code, i.e.:
#if GTK_MAJOR_VERSION > 3 || (GTK_MAJOR_VERSION == 3 && GTK_MINOR_VERSION >= 4)
At least they should be the same so someone reading the code can see that they are related.
We don't have that style when checking Gtk+ versions in other places, so introducing it here just makes the code harder to read.

Good point. Glibc has a good style here; it defines macros
__GNUC_PREREQ, __GLIBC_PREREQ, etc., to check version numbers.
I added a macro GTK_PREREQ to do that with the similar uses
for GTK version numbers, as trunk bzr 112523. Please feel
free to change it if you still find it confusing.

Good idea. But you missed one in gtkutils.c.

I also missed the fact that GTK already defines a version-checking
macro. I fixed both problems in trunk bzr 112533.
