[Qemu-devel] timer in vl.c

[Maarten Boekhold <boekhold@emirates.net.ae>]

Hi all,

I'm trying to port qemu so it compiles on cygwin, and I'm having a bit 
of trouble with vl.c.

vl.c defines start_rtc_timer() and init_timers(). If I read it 
correctly, the code says something like (only put code that I believe is 
relevant to this question down below):

#ifndef _WIN32
#if defined (__linux__)
static int rtc_fd
static int start_rtc_timer(void) {
...
}
#else
static int start_rtc_timer(void) { return -1;}
#endif
#endif

static void init_timers(void) {
#ifdef _WIN32
...
#else
 /* here rtc_fd is referenced */
#endif
}

How does this work when you try to compile on a BSD platform? On such a 
platform, rtc_fd won't be defined, yet the code that references it will 
be compiled, no?

CVS from june 7
