good, which execution model are you using (iterative, fork or pre- 
fork) ?

$ m68k-elf-gcc -v
gives 2.95.3.

This GCC version does not support mixing declarations and statements  
in the function body (which comes with GCC 3), hence all your  
variables must be declared within the <%! /* declaration block */ %> .

For a better understading, take a quick tour in the klone-2.0.2/build/ 
target/klone-core-2.0.2/site/ directory and search for the translated  
kl1 pages (the C files with the pg_ prefix) to see how the C/C++ code  
you write is reassembled into the exec_page() context.

Two (untested) options are:

1) change the CC variable in toolchain from m68k-elf-gcc to m68k-elf-g+ 
+ (flags should be compatible)
2) change your pages' extension from .kl1 to .klx (which automatically  
switches to the C++ compiler)
