Bug#893756: ignition-common: FTBFS on hurd-i386: PATH_MAX not declared

[Aaron M. Ucko]

Source: ignition-common
Version: 1.0.1-1
Severity: normal
Tags: upstream
User: debian-hurd at lists.debian.org
Usertags: hurd

The build of ignition-common for hurd-i386 (admittedly not a release
architecture) failed:

  /<<PKGBUILDDIR>>/src/FilesystemBoost.cc: In function 'std::__cxx11::string ignition::common::cwd()':
  /<<PKGBUILDDIR>>/src/FilesystemBoost.cc:134:25: error: 'PATH_MAX' was not declared in this scope

The Hurd makes a point of not having a static PATH_MAX.  Best practice
is dynamically accommodating whatever you actually encounter, for
instance by taking advantage of realpath's policy of allocating the
buffer itself when supplied a NULL buffer.  (You'll of course need to
free it when done.)

Could you please take a look?

Thanks!
