Jeff, I am a little lost in that code as you might imagine :-)
BTW, the HAVE_MMAP is defined.
I set a breakpoint at "uprv_mapFile_2_6", and here is some of the gdb debug...
[New Thread 16384 (LWP 942)] [Switching to Thread 16384 (LWP 942)]
Breakpoint 1, uprv_mapFile_2_6 (pData=0xbfffd9e0,

Continuing.

^^^^^^^^^^^^^^^^^^^^ I DONT LIKE THIS but maybe is just me :-) shouldn't we have an open fd again, or that close should be there? :) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
