Re: [Bug-apl] Android code compatibility issues

[Juergen Sauermann]

Hi Elias,

I have removed langinfo.h (a left-over from internationalization which I 
removed earlier, SVN 307.

shm_open() and shm_unlink will go away long-term because I will move the 
shared memory database to a
separate thread. Just didn't have enough time yet to do that.
