[Ecls-list] unknown symbol: mp::interrupt-process / We cannot use the mmap code without siginfo

[Dr. David Kirkby]

I'm having a hard time on Solaris and OpenSolaris building the libecl.so library 
without text relocations against non-writable segments. This basically makes the 
ECL library unusable on 64-bit Solaris/OpenSolaris.

I know the same issue arises with 3 library used by the stats package R if one 
uses gcc, but the problem disappears if one uses the Sun compiler.

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

I'm using

  * Sun Ultra 27
  * 3.33 GHz Intel Xeon
  * Sun Studio 12.1

Any ideas how I might fix this?
