I think this template could use a better refactor. Also, what are the differences between the C and fpc engine?

Some suggestions:

• only add fpc in hostmakedepends conditionally instead of sed'ing it away
• don't conditionalize the C engine for ppc*, instead use it for everything except x86_64, as a single case, since fpc is only available on x86
• for the cflags removal, conditionalize it with some kind of $_use_c variable and set _use_c=yes when using the C engine

Thank you for the suggestions. I wasn't aware of the state of fpc on other archs, that's good to know, it would be nice to fix it for as many as possible.

Pas2C is an alternative way to build the engine. It is disabled by default.

Pas2C is intended to be used when building the engine natively (e.g. with FreePascal) fails for some reason. However, Pas2C does have some limitations and you should try to first build Hedgewars normally before attempting a Pas2C build.

Pas2C is our hand-written Pascal-to-C-compiler. It works by converting all Pascal code to C, and then compiling the C code with a C compiler. Pas2C itself is written in Haskell. Yes, we're a little crazy. :-)

The Pas2C build currently doesn't support the video recorder.
