I had the same issue on HP-UX and I can confirm this was an issue with tar and
long file names.

----

On Linux:
# tar --version
tar (GNU tar) 1.13.25 ...
# tar tvfj gcc-4.2.1.tar.bz2 | grep hash_load_check_resize_trigger_imp.h
-rw-rw-r-- mitchell/mitchell    8616 2006-11-08 12:57:52
gcc-4.2.1/libstdc++-v3/include/ext/pb_ds/detail/resize_policy/hash_load_check_resize_trigger_imp.hpp

On HP-UX:
# tar --version
tar (GNU tar) 1.13
# tar tvf gcc-4.2.1.tar | grep hash_load_check_resize_trigger_imp.h
-rw-rw-r-- mitchell/mitchell    8616 2006-11-08 12:57
gcc-4.2.1/libstdc++-v3/include/ext/pb_ds/detail/resize_policy/hash_load_check_resize_trigger_imp.hp

(note the missing "p" at the end)

----

What happens then is that in the build tree, the
hash_load_check_resize_trigger_imp.hpp file gets linked to itself:

root@bct_hp8:/packages/gcc/build-gcc421
# ls -l
./hppa64-hp-hpux11.11/libstdc++-v3/include/ext/pb_ds/detail/resize_policy/hash_load_check_resize_trigger_imp.hpp
lrwxrwxrwx    1 root          114 Sep 25 16:19
./hppa64-hp-hpux11.11/libstdc++-v3/include/ext/pb_ds/detail/resize_policy/hash_load_check_resize_trigger_imp.hpp
->
/packages/gcc/gcc-4.2.1/libstdc++-v3/include/ext/pb_ds/detail/resize_policy/hash_load_check_resize_trigger_imp.hpp

There are two such files in the source tree:
# find -name \*.hp
./libstdc++-v3/include/ext/pb_ds/detail/resize_policy/hash_load_check_resize_trigger_imp.hp
./libstdc++-v3/include/ext/pb_ds/detail/bin_search_tree_/constructors_destructor_fn_imps.hp

The second one triggers the same kind of error than the first.

Changing the suffix of those two files to .hpp in the source tree fixed (that
part of) the build for me.
