Problems with libdivecomputer under OSX

[Pascal Manchon]

Jef, 

To follow your request, I just did 2 tries on compiling libdivecomputer on my native OSX 64bit environment :

First try without options (compiles for 64bit) :
$ ./configure
$ examples/vyper /dev/tty.usbserial-PtTFP8W4 
DEVICE=/dev/tty.usbserial-PtTFP8W4, DELAY=500
suunto_vyper_device_open
TRACE (serial_posix.c:684, ioctl): Inappropriate ioctl for device (25)
suunto_vyper.c:145: Failed to set the DTR line.
suunto_vyper_test.c:38: Error opening serial port.
suunto_vyper_device_open
TRACE (serial_posix.c:684, ioctl): Inappropriate ioctl for device (25)
suunto_vyper.c:145: Failed to set the DTR line.
suunto_vyper_test.c:71: Error opening serial port.

Second try with :
$ export CPPFLAGS=-m32
$ export LDFLAGS=-m32
$ ./configure --build=i686

and this seem indeed to work correctly (at least the computer starts dumping its memory)

What actually made me try the unsigned long type is the man page for ioctl : https://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man2/ioctl.2.html#//apple_ref/doc/man/2/ioctl
