I think I found an issue with convimg. In CEdev/examples/combined/appvar_tilemap, there's, well, an example usage for tilemap appvars. When given the already made 'vargfx.c' and 'vargfx.h' in src/gfx/, the program compiles fine. However, if you open cmd and run 'convimg.exe' inside the 'gfx' directory, the code will no longer compile and will complain about vargfx.c. Upon closer inspection:

Original code in 'vargfx.c' in CEdev/examples/combined/appvar_tilemap/src/gfx:

Code in "vargfx.c" when recompiling gfx using comvimg:

Besides the spacing in the second document, I don't see any difference between the two code-wise. However when trying to compile the code, I get a syntax error at line (170,3).... which is a blank line.

I found this out while I tried creating my own tilemap appvar for a game, and the compiler was complaining about a blank line in "<appvar>.c" I then went to the examples in the toolchain and ran this experiment.

It doesn't like the semicolon at the end.
Fix by recompiling convimg.

Thank you.
