Hi,
Currently doxygen FTBFS on GNU/Hurd due to a PATH_MAX issue.
The attached patch, filesystem_filesystem.hpp.diff, fixes the build
problem by special-casing for Hurd. In fact the patch could be applied
to all glibc-based systems and upstreamed.
However, it is not very C++-ish, maybe some better solution could be
used. Cc-ing bug-hurd for comments, WDYT?
Thanks!
