Thiago is right..
The only major problem is under sound applications that relies over cdrom.h 
Linux Header that includes :

In file included from /usr/include/linux/byteorder/little_endian.h:11,
                 from /usr/include/asm/byteorder.h:45,
                 from /usr/include/linux/cdrom.h:14,
                 from CdboDevice.cpp:34:
/usr/include/linux/byteorder/swab.h: In function `const __u32
   __fswab24(unsigned int)':
/usr/include/linux/byteorder/swab.h:174: error: ISO C++ forbids braced-groups
   within expressions

Was explained to me that the header itself is a very common implementation 
under Linux kernel, and is a gcc-ism, so -pedantic will not work.
I Agree with Coolo that we do not must remove it, since the ut not generated 
can hide ugly flaws.
One of the our kernel hacker told me to do a C++ implementation of cdrom.h 
header to avoid this, but believe that can be worst than remove -pedantic. 
So, can anyone bring a better idea ?
