There is not a method 2. The 4 numbered paragraphs describe in which
directories the search for an include file happens. The hardcoded
library directory described in paragraph 2 is determined in the
corresponding makefile and in "seed7/src/infile.c". Interpreter and
compiler use the same strategy to search for an include file.

BTW.: I have improved the FAQ. Please take a look at

  http://seed7.sourceforge.net/faq.htm#lib_path

and tell me your opinion about it.

Interpreter and compiler may have problems to find the include
directory in two situations:

 1. The directory "seed7/lib" was move to a different place after
    the Seed7 interpreter was compiled.
 2. The binary release of Seed7 is used and the current working
    directory is not "seed7/prg".

In both cases the problem can be solved with the environment
variable SEED7_LIBRARY. Just set SEED7_LIBRARY to the path of the
directory containing the include/library files (without surrounding
quotes). E.g.: /home/abc/seed7/lib
How to set an environment variable depends on the operating system
and shell (see: http://en.wikipedia.org/wiki/Environment_variable ).

Currently there is a restriction for the environment variable
SEED7_LIBRARY: The path must consist of ASCII characters (LATIN-1 
characters might work also, but I have not tested it).
