Обсуждение: Docu question

In manage-ag.sgml our docs says:

[...]   risk. To allow it, you must compile <productname>PostgreSQL</> with   the C preprocessor macro
<literal>ALLOW_ABSOLUTE_DBPATHS</>  defined. One way to do this is to run the compilation step like   this:
 
<programlisting>
gmake CPPFLAGS=-DALLOW_ABSOLUTE_DBPATHS all
</programlisting>
[...]

I wonder if there's a reason to suggest this gmake call. After all it
makes gmake disregard the CPPFLAGS settings in the Makefile. This for
instance breaks ecpg compilation on Linux as -D_GNU_SOURCE as defined in the
Makefiles is needed for LONG_LONG_MIN.

I think we should either change the docs or start using "override" in
the Makefiles.

Agreed. This is a problem.
