configure patch for building with Solaris

Hi list,

A couple of changes in configure so that it builds in Solaris. It checks if os = solaris and CC = gcc and releaves the requirement for gnu99 compiler (gcc after all is). Definition of gnu99 clashes with Sun's definition of HUGE_VAL in /usr/include/iso/math_c99.h

Can someone explain me why the sudden interest for gnu99 compiler? It didn't used to be so in 1.4.1 and kannel was compiling fine back then.

BR,
Nikos
