 The build that is used is the build with softfloat support (it's the 
 only one we provide), which may be the only one that is affected by the 
 recent bug(s), i.e. it is used as a starting compiler (in the original 
 email). Further, reading Sash0k's original email again, he might be able 
 to avoid the issue by cross-compiling a start compiler to ARM from a 
 current trunk compiler enabling VFP (hardware FP) support. See 
 http://wiki.freepascal.org/iPhone/iPod_development#Building_an_ARM_Cross-compiler 
 for ideas.

 Btw, I'm not sure what FP type is using in his build because he does 
 not specify.

 Delphi cross-compiles too, so it might be okay.
