I'm having a hard time on Solaris and OpenSolaris building the libecl.so library<br>

Hence I'm trying to build the latest git snapshot (downloaded around 1900 GMT on<br>
28th October 2010) using the Sun compiler. But the Sun compiler will not compile<br>
this - it is failing with:<br>

line 97: #error: "We cannot use the mmap code without siginfo"</blockquote></div><br clear="all">mmap is used in ECL to help in delaying interrupts. The trick is simple: ECL gets an interrupt while executing a C function that can not be interrupted, it marks (using mmap) the Lisp environment as read-only, ECL tries to write to the environment after the C function finished, this causes a signal and now it can be processed together with the pending interrupts. But this only works when mmap implements interrupts with information.<div>
