#203 Fix build on Open Solaris

[Florian Sesser]

streamripper-1.64.6 doesn't build on OpenSolaris (svn_130) because of

ripstream.c:717: error: `__uint32_t' undeclared (first use in this function)

That is the only occurence of a __uint32_t. Changing it from "__uint32_t" to "unsigned long int" made the build work for me.

(That is, I replaced

#ifndef WIN32
__uint32_t framesize = 0;
#else
unsigned long int framesize = 0;
#endif

by

unsigned long int framesize = 0;

)

Thank you for streamripper! Great piece of software.
