annotate docs/html/sdlcdplaytracks.html @ 3917:8a3a0f1179f3 SDL-1.2
Patched fbcon to compile on newer Linux kernels that don't #define PAGE_SIZE,
since a memory page's size may vary on various architectures and kernel
configurations.
Will use getpagesize() if it exists, the PAGE_SIZE #define from older kernels
if that doesn't, and #error out if that's not there either...but it's
probably 4096 in that case. We may revisit this.
Fixes Bugzilla #392.
