[Dev-C++] Strange compilation unit errors

[Scott S. <ssi...@sp...>]

I am working on a TGA file loader for OpenGL. I keep getting lots of 
errors. It looks like the header file for the TGA loader isn't being 
seen, so the definition cannot be found. Does anyone know why it isn't 
working? Its about 130 lines of code or so, and is at 
http://home.comcast.net/~ageofscott/tgacode.zip
compilation errors are below:

Thanks in advanced for any help.
