[Bug-wget] Wget build system.

[illusionoflife]

Hello!
Currently I am trying to get used to
wget source base and found something strange.
When I am building from directory, other than $(top_srcdir),
I get configure error:
        config.status: linking ../GNUmakefile to GNUmakefile
        config.status: error: ../GNUmakefile: file not found
When I build from $(top_srcdir), build successfull, but check
returns this:
==================
69 tests were run                                                               
                                                       
9 PASS, 0 FAIL                                                                  
                                                       
60 SKIP, 0 UNKNOWN                                                              
                                                       
==================         
Only 9 tests run?! I find it strange.
Also, I find strange that configure.ac 
contains deprecated macros. Should I replace them with modern one
or there is deep mind about it?
Also I think that code in $(top_srcdir)/src should not contain
(5) files, containing main() function. 4 of them are tests, and, unless I am 
missing something, I should move to $(top_srcdir)/tests.

As I understand it, .px files are analoges for autotest suite and
#ifdef TEST is like check, am I right? 
Thanks for patience in forward. Never worked with big project.
