hurd builds

[Simon Josefsson]

I'm trying to get gnulib to work on the Hurd, and ran into this in
test-getcwd.c:

test-getcwd.c: In function 'test_long_name':
test-getcwd.c:119:11: error: missing binary operator before token "("

The code is:

    29  #include "pathmax.h"
...
   108  static int
   109  test_long_name (void)
   110  {
   111  #ifndef PATH_MAX
   112    /* The Hurd doesn't define this, so getcwd can't exhibit the bug --
   113       at least not on a local file system.  And if we were to start 
worrying
   114       about remote file systems, we'd have to enable the wrapper function
   115       all of the time, just to be safe.  That's not worth the cost.  */
   116    return 0;
   117  #elif ((INT_MAX / (DIR_NAME_SIZE / DOTDOTSLASH_LEN + 1) \
   118          - DIR_NAME_SIZE - BUF_SLOP) \
   119         <= PATH_MAX)
   120    /* FIXME: Assuming there's a system for which this is true,
   121       this should be done in a compile test.  */
   122    return 0;

In pathmax.h, gnulib sets up a PATH_MAX like this:

#  define PATH_MAX (pathconf ("/", _PC_PATH_MAX) < 1 ? 1024 \
                    : pathconf ("/", _PC_PATH_MAX))

And of course the #elif fails because PATH_MAX isn't a constant
expression.

It seems weird for test-getcwd.c to include pathmax.h and then do a
#ifndef PATH_MAX test?
