Please do not use MAXPATHLEN, it is a arbitrary limit, and is not defined on GNU. Currently gcc 4.0.0 is unbuildable on GNU since [gcc]/gcc/tlink.c assumes that MAXPATHLEN is defined. Please do not use these kind of limits in GNU programs.
Suggested fix is to declare initial_cwd as: char *initial_cwd; and then instead of doing: getcwd (initial_cwd, sizeof (initial_cwd)); do: initial_cwd = getcwd (NULL, 0); Note: getcwd (NULL, 0) is a GNU extention, and might not be available on non-GNU platforms. (End of Note) Sorry for not supplying a patch, happy hacking. -- Summary: MAXPATHLEN usage in [gcc]/gcc/tlink.c Product: gcc Version: 4.0.0 Status: UNCONFIRMED Severity: critical Priority: P1 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: ams at gnu dot org CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: i686-pc-gnu0.3 GCC host triplet: i686-pc-gnu0.3 GCC target triplet: i686-pc-gnu0.3 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21706
