bug#10677: 24.0.93; missing pathmax.h on Solaris

[Chong Yidong <cyd@gnu.org>]

I received the following compile failure on Solaris (SunOS 5.10).

Paul, could you investigate?  Thanks.  (Keeping my fingers crossed that
the proferred solution is not going to be a Gnulib sync ;-)

Hi, I'm attempting to compile Emacs 24.0.93 on my work Solaris box but
pathmax.h is not found.

Uname -a reports
SunOS morocco 5.10 Generic_127111-11 sun4u sparc SUNW,Sun-Fire-V490 Solaris
I'm compiling with gcc --version
gcc (GCC) 3.4.6

I'm afraid I have no control over the system software that's installed
here...  That's why I compile into my home directory.  This exact same
machine compiled Emacs 23.3 without any problems at all.

The configuration is nothing special:
bash-4.1$ ./configure --prefix=/home/leyon/contrib
--with-x-toolkit=lucid --with-gif=no

The exact error is:
bash-4.1$ make
[ -r "/home/leyon/morocco/emacs-24.0.93/src/config.in" ] || ( cd
/home/leyon/morocco/emacs-24.0.93 && autoheader )
cd lib; make all                            \
  CC='gcc -std=gnu99' CFLAGS='-g -O2' CPPFLAGS='' \
  LDFLAGS='-L/usr/openwin/lib' MAKE='make'
make  all-am

If you would like any further information I'd be happy to assist.
