In wc_to_utf8() in windows.c, the zero terminator is written to an invalid
array index, which results in 2 bytes being zeroed in a random place in the
stack. This sometimes causes a crash when running sp_list_ports() (depending
on string length and compiler optimisation settings).
sizeof(wc_str) returns the size in bytes, so cannot be used directly as an
index into that array, it should be divided by sizeof(WCHAR). Otherwise the
zero terminator index is approximately twice what it should be.
This fixes bug #1031.
readir() is threadsafe on both linux and freebsd anyway.
The rationale behind the readdir_r() deprecation is in the glibc manual:
https://www.gnu.org/software/libc/manual/html_node/Reading_002fClosing-Directory.html
This fixes the following warning with recent glibc:
linux.c: In function ‘list_ports’:
linux.c:197:2: warning: ‘readdir_r’ is deprecated [-Wdeprecated-declarations]
while (!readdir_r(dir, &entry, &result) && result) {

Buildroot can create toolchains for the no-MMU flavour of Linux, with a triple
containing 'uclinux' instead of just 'linux'.

We want to check here if we added something to the list, not if the

The last release (0.1.0) had the libtool version (current:revision:age)
set to 0:0:0. Since this release doesn't change/remove any
interfaces (it does *add* new interfaces, though), 'current' and 'age'
are increased and 'revision' is set to 0, resulting in 1:0:1.

Programs using libserialport don't need to be recompiled or relinked.
USB composite devices can contain an ACM serial interface.
On Windows, the correct iSerial descriptor field is assigned to the parent
(composite) device instead of to the actual serial interface. A bogus
value is returned if the serial interface is asked to provide the S/N.
This patch provides a fallback for this kind of device (tested on Android
with adb + cdc gadgets and on Arduino Zero Programming Port)
On OSX 10.11 (ElCapitan) the query for IOProviderClass fails to list ACM
devices as USB.
Add a fallback query using IOClass to correctly recognize these devices.
The fix has no effect on previous OSX versions (tested on Mavericks)
Use autoreconf instead of invoking the various Auto tools
separately. Get rid of the Darwin-specific guesswork -- it does
not make sense to handle this at the level of libserialport.
People should set up their ACLOCAL_PATH themselves as appropriate
for their own system; just as they already need to set up various
other paths.
