When things go well, config.log becomes irrelevant.  It helps when  
things do not go well, as now.  Also, "obvious" is a very relative  
term.  Once you have much more experience tracking down problems like  
this, you will recognize that those particular errors are really not  
important at all (more below.)

It should not be necessary, but don't try to extract single lines.   
Post the contiguous set of the last twenty or so lines before:

## ---------------- ##
## Cache variables. ##
## ---------------- ##

Don't do any additional editing.  Those errors about -V are really not  
important,  They are errors from gcc which tell configure about which  
gcc features are or are not present.  While running, configure creates  
lots of small test programs which it tries to compile, and it uses the  
results (very often compile failures) to know what features are  
available, which it uses to create the Makefiles which are then used to  
compile the program you are interested in.  (Remember, configure can  
handle a whole bunch of different compilers than gcc and different OSs  
than Linux.)  I'm looking for the lines from config.log instead of the  
console because they generally have additional information.
