Q about 2.3.12 compile error messages

[Hans Forbrich]

'make all' on 2.3.12 on SuSE 8.2 results in the following output snippets.  
Please advise whether these are significant - 'make install' seems not to be 
affected.  My config at bottom.

(I've included the make line immediately before messages - hopefully that will 
help isolate the location.)
