-- from lib-util.adb:

Info_Buffer : String (1 .. Max_Buffer);

so, (2 * 1024 + 64) * 1000 = 2112000 bytes = 2062.5K.
$ nm lib-util.o | grep info_buffer
00203a00 C lib__util__info_buffer
and hex 203a00 = decimal 2112000.

Surely there's some form of dynamic allocation you could use for this,
though. Or just not buffering the file in such huge chunks? C stdio
tends to use buffers on the order of a memory page...
