New description:
The latest version of the Lisp interpreter ECL, (which is used by Maxima)
is 11.1.1, but the version of ECL in Sage is 10.4.1.
Version 10.4.1 is the source of one really major problem on 64-bit
!OpenSolaris (see #9840), as it creates a broken library libecl.so, which
can't be linked to. This stops Sage building as a 64-bit application.
The failure of ECL to build a fully functional 64-bit library is due to
non-PIC code being present, which itself was the result of the use of a
GCC extension of "computed gotos" in the ECL source code.
http://gcc.gnu.org/onlinedocs/gcc-4.5.2/gcc/Labels-as-Values.html
The updated ECL avoids this GCC extension on Solaris, with a result the
library has no text relocation issues.
An updated .spkg for ECL can be found at:
http://spkg-upload.googlecode.com/files/ecl-11.1.1.spkg
It is also necessary to update Maxima at the same time. The ticket for
Maxima is #10773 which already has positive review.
