[ale] Confusion compiling new software

[Thompson Freeman]

Ok. I've messed something up here, and don't know what.  
Also, I may not know enough of what I'm doing to give  
entirely coherent descriptions.

Still, if anybody has a clue, I sure would like to borrow  
it for a while...

For much of the day, I have been compiling, trying out,  
then recompiling a new application with different  
configurations & libraries. This application comes in two  
parts, a library portion, and what supposedly is the user  
interface portion. The library can link in two optional  
libraries, and the user interface can link in four optional  
libraries. (All these optional libraries are why I'm doing  
the compile/recompile exercise; trying to note which does  
what and so forth). The configure;make;make install; make  
uninstall has been working for about six iterations now  
while I try to learn what I'm doing.

Unfortunately, the configure step just blew up on me with  
the line "checking for C compiler default output file  
name... configure: error: C compiler cannot create  
executables"  I attach the config.log for more details.

Any body know/guess what I've done wrong???

Help!
