  Easy to fix, but I have no idea what is going on there; maybe you should  
document it.

  That should be fixed now. Note that Makefile.in shouldn't be present in  
the SVN, because it's generated by configure (I guess...) from Makefile.am.

  Details:
- added to includes: src/math/
- added to libraries: src/libtechmath.la and -lkdeutil (maybe some other  
lib from KDE would be enought, I don't know).
  All these are defined in Makefile.am.

  After running the test program, I got "nan FAIL =(". Start the debugger...

  Btw. linear algebra: there is some code to dump the equations of a  
circuit. To use it, one needs to open a circuit document and add the "Dump  
linear equations" to the toolbar. It shoudld work also with the Ctrl + D  
key combination, but it seems that only if it's placed on the toolbar. The  
output of this function has an issue: kdDebug() and cout is mixed in the  
code, so expect strange breaks in the text. Maybe only kdDebug should be  
used; it's quite easy to fix.
