[pkg-boost-devel] Bug#487343: boost: FTBFS on hurd-i386 because of unconditionnal PATH_MAX usage

[Samuel Thibault]

Package: boost
Severity: important
Tags: patch

Hello,

boost currently FTBFS on hurd-i386 because it unconditionnally uses
PATH_MAX in pwd.c.  The attached patch fixes that by taking advantage of
glibc's get_current_dir_name().
