Comment # 4 on bug 1049382 from Bernhard Wiedemann

using strace -f showed that geany creates a /tmp/tmp_XXXXXX.cpp
in src/tagmanager/tm_workspace.c
and that uses a g_hash_table in its lookup_includes function
to write .h files in indeterministic order into the tmp cpp file.

There is also a tm_file_inode_hash function using the st_ino field from g_stat
output - and inode numbers are certainly varying across builds.
