Thanks Jonas. Below are SPARC-specific issues that I'm aware of, this is 
for the benefit of anybody from the Solaris/OpenIndiana communities and 
I'm most definitely not trying to criticise project management.

0020072: Floating-point register allocation for doubles [Noted by Marco 
as being backported.]

0020397: Variant returns wrong Int64 value on SPARC. [Marked as fixed in 
2.7.1, don't see any problem in 2.6.0.]

0020153: Bus error when compiling trunk (18976) on SPARC etc. [Ditto.]

Practical experience suggests that Lazarus 1.0 + FPC 2.6.0 is OK (the 
program that showed up the above appears to work as expected). Residual 
issues:

0020396: Signed 32-bit multiplication raises an overflow exception if 
result -ve [Still in 2.6.0 and 2.6.1. OK in 2.7.1.] For the time being, 
don't use -Co or the equivalent Lazarus project setting.

0020240: Arithmetic exception when compiling fp+gdb on SPARC [Possible 
duplicate of 0020265: Compiler crashes with SIGFPE, which is marked as 
fixed in 2.7.1 but might still be a problem in 2.6.0.] For the time 
being, don't use the FP IDE's libgdb interface.
