after removing HAVE_* stuff from sysconfig.h we get past the missing includes and get

thanks for filling issue , it's better way than msg.
Btw ,despite the fact i have no time to finish GUI, I m working on the nulkear gui version of this core
https://github.com/r-type/frodo-libertro-nuklear/blob/master/libretro/emu/Display_retro.i

screen=(retro_Surface*)malloc( sizeof(retro_Surface*) );

should solve the fisrt above error

BTW as stated i have no much to support this core , and it should tricky to correct it for building on osx (as i don't know about that os),
you have to solve yourself (or someone who can build on osx) the osx specific stuff like sigaction ,vfs ...equivalent
