Wouldn't it be cleaner to say in some strategic place (like a header
included by many sim files)

 #ifndef HAVE_LSTAT
 #define lstat stat
 #endif

and then leave the *.c files alone?  I think this is a better
solution, and include/gdb/callback.h seems like a good place to do
that.

Perhaps it's even something MinGW headers should do for you, but for
now a GDB solution will be fine.

`ftruncate' is a very simple function; you could write an emulation
using `lseek' and `write'.  (If you want, I can show you the
implementation from the DJGPP library.)  I think it's better to add
such an emulation that to fail the calls.
