Hi, The attached patch implements the scm_init_guile function on Solaris. The detection of the stack parameters is done via a new(ish) Solaris function, stack_getbounds() -- see http://download.oracle.com/docs/cd/E19253-01/816-5168/stack-getbounds-3c/index.html for details.
Tested on Solaris 10u9, on both SPARC64 and x86_64. - Andrew PS: now, on to get 2.0.1 working...
