Those are compiler flags for the Sun compiler. Not a lot of help with gcc.

Sage now builds on OpenSolaris 32-bit, and passes all the Sage test suite.

That looks to be true.

But Solaris 10 has not died, neither or x86 or SPARC. The issues are seen on 
Solaris 10 SPARC too, so it not just an x86 problem. Maxima is not complaining 
on SPARC, but the elfdump command clearly shows the problem is in the ECL 
library file. That problem exits on 64-bit SPARC  too.

Two of the parts of Sage that are showing problems on 64-bit Solaris/OpenSolaris 
buids (ECL and Cliquer) give an output from that command above. So if the 
link-editor thinks a file contains non-pic code, then it will present a problem.

The problem can't be Maxima, as I don't need to even build Maxima to show the 
ECL code has this problem.

The MPIR library does not exhibit this issue.

Neither do most others. The only offenders in Sage are ECL, PolyBoRi and Cliquer.

Sorry, the title is a bit confusing. The problem is seen

  * 64-bit SPARC
  * 64-bit Solaris 10 on x86
  * 64-bit OpenSolaris on x86

Note also, I built your latest sources outside of Sage. The issue is seen there.

Note also, that there's this compiler warnings when I build on Solaris (or any 
sort)

warning: too many arguments for format

When I use the debugging technique mentioned at

http://blogs.sun.com/rie/entry/my_relocations_don_t_fit

$ export LD_OPTIONS=-Dreloc
$ make

and look at the resulting output, it indicates to me, the problem is with dpp.c 
- which maybe coincidence, or maybe not, is the same file giving a compiler 
warning.
