Hello, dear author, I have some questions I'd like to ask. In the C implementation part of your project, could you please explain the differences between WGS72 and WGS84 in the SGP4 code and why WGS72 is used in the code instead of WGS84?

Hey, what are your thoughts on making the C library ANSI (C90) compliant?

The following changes would be required:

• Replace C++-style comments (//) with C-style comments (/**/)
• Move declarations to the start of code blocks (already occurs in most of the code)
• Replace %lf format specifier with %f in printf in TestSGP4.c

I'd be happy and make these changes, so feel free to assign the issue to me.

Hello, on line

Suggest some clean-ups to remove compiler warnings... I applied this locally in a "c-code_clean-up" branch...
