The include files for 1.3 - which are picked up by the compiler if `-mcrt=nix13` is used - can be found at `<PREFIX>/m68k-amigaos/ndk13-include` i.E. `/opt/amiga/m68k-amigaos/ndk13-include`
## Libraries/Runtimes
You can select one of the various runtimes. My favorite is `libnix` which is selected by specifying `-noixmeul` or `-mcrt=nix20`. Always specify this as the last parameter and only once. These are the available runtimes:
* nothing specifed: newlib based libraries for Kickstart 2.0+
* `-noixemul` or `-mcrt=nix20`: the libnix libraries for Kickstart 2.0+
* `-mcrt=nix13`: the libnix libraries for Kickstart 1.3
* `-mcrt=clib2`: the clib2 libraries.
* `-mcrt=ixemul`: the ixemul libraries for Kickstart 2.0+, requires an installed `ixemul.library`
## Checking gcc
To check the built version you may consider to run the gcc dejagnu tests. This does not cover everything but it's a start.

### Notable branches
* `amiga6`: The default branch providing gcc-6.5.0b with a lot of hacks^^
* `amiga13.1': gcc-13.1.0 supports register parameters
* `amiga13.2': gcc-13.2.0 supports register parameters
* `68080regs`: gcc-6.5.0b supporting the B0-B7/E0-E7 AMMX registers of the Apollo 68080 (experimental)
## Fortran support
m68k-amigaos-gfortran is available now too. To build it add `ADDLANG=fortran`:
