I cloned binutils-gdb repository from here (master branch) on a linux
machine (Ubuntu) and I want to compile it for Windows (using
x86_64_w64_mingw32 toolchain).
First, I ran ./configure with the following options to specify the
cross-compile toolchain.
./configure --prefix=/usr/x86_64-w64-mingw32 --target=arm-none-eabi
--host=x86_64-w64-mingw32
Then I ran make and get the following error (I omitted most of the output
because it is pretty large):

I think it has something to do with time_t being typedef'd as a long long
int (64 bit integer) in the host platform (Windows), however, the function
os_time from the file sim/common/callback.c:414 (path relative to project
root), takes a long (32 bit integer) as a parameter:
static longos_time (host_callback *p, long *t){
return wrap (p, time (t));
}
How can I fix this error?
