Hi, attached there is a patch for autogen to fix the definition of MAXPATHLEN when not defined already (either not directly or because PATH_MAX is not defined either). This caused a build failure in sharutils (which embeds the libopts part of autogen) on GNU/Hurd (which provides no PATH_MAX nor MAXPATHLEN) [1]. This happens because in autogen's autoopts.h there is: # if defined(PATH_MAX) && (PATH_MAX > MAXPATHLEN) which triggers a preprocessor parsing error when MAXPATHLEN is defined as (size_t)4096. [1] https://buildd.debian.org/status/fetch.php?pkg=sharutils&arch=hurd-i386&ver=1%3A4.13.5-1&stamp=1381663210 Thanks, -- Pino Toscano
