Compilation maybe broken in ALSA (juce_linux_ALSA.cpp)

Linux

Hi,

Today i've update JUCE > 4.02 on my linux distro :

> Linux 3.2.0-75-generic i686 Ubuntu
> GCC 4.8.4
> Codeblocks 13.12

This is the codeblocks build log :

When I change the line 649 from

void waitForDevice (snd_pcm_t handle)

to

void waitForDevice (snd_pcm_t* handle)

The compiler build is fine.

Don't know if is my distro or not. Let me know if I doing something wrong.

Regards to JUCE team !

Oops, seems like our module updater script failed and the wrong version of that file ended up in the zip file. We've sorted it out now if you want to re-download them.
