You can use the -Un command line option, in which case the compiler  
will not check that the unit name matches the source file name. In  
this case, you have to explicitly mention the source file name every  
time you use this unit though, since otherwise the compiler won't be  
able to find it. See e.g. http://svn.freepascal.org/svn/fpc/trunk/tests/webtbs/tw1279.pp 
  and http://svn.freepascal.org/svn/fpc/trunk/tests/webtbs/uw1279.pp
