This is in "src/config.mak", not in "src/Makefile".

It also took me a while to figure this out.  IUP offers you two totally 
independent build options, namely 'tecmake' and 'premake'.

"Tecmake" is simply a Makefile for GNU make that includes "config.mak", 
so "config.mak" contains all necessary definitions for compiling IUP. 
This seems to work fine (and I would recommend using tecmake for 
building IUP).   The Tecmake package is linked from the IUP homepage. 
It contains a number of files, but you really only need "tecmake.mak" 
(the GNU make Makefile) and the script "tec_uname.bsh" (which tells you 
what environment variables to set).

"Premake" is a Lua program that reads "premake.lua" and generates 
"Makefile" and "iup.make".  The error is in "premake.lua" (it simply 
puts all *.c files in the package).  I was unable to find a copy of the 
premake program that works with the "premake.lua" files in IUP, so I 
didn't really try this out.    I would recommend against working with 
the pregenerated Makefiles (unless of course they just happen to work 
for you if you have exactly the right environment).
