* src/lib/Evil.h: 

* src/lib/evil.c: (evil_last_error_get):
add evil_last_error_get() function to get
useful error string creation.
* src/lib/dlfcn/dlfcn.c: (get_last_error), (dlopen), (dlsym),
(dladdr):
use UNICODE check instead of compiler checks when needed.
use evil_last_error_get()
* src/lib/mman/mman.c: (mmap), (munmap):
file mapping does not work on Windows CE < 5.0.
if it is the case, just read the file and return
the data.
use evil_last_error_get()
* src/lib/mman/Makefile.am:
* src/lib/Makefile.am:
add libevil dependancy
