#2 portability on solaris

[Anonymous]

I got compilation errors on Solaris. However, they
could be resolved easily. This is how:

1) mp3asm.h includes argz.h which is a glibc feature
not available on Solaris. However, it is not needed
anyway. So i simply removed the include.

2) utils.c complained about undeclared ENOMEM and
errno. I simply included errno.h and it worked.
