It seems that version of ICU_531 in <http://www.stats.ox.ac.uk/pub/Rtools/goodies/> as of June 25, 2014, was compiled using sjlj exception handling (current gcc-4.6.3, perhaps?). I say that as I am trying a 4.9.2 distribution which uses seh handling, and I get errors like:

Is there any intention to recompile the ICU pack in the goodies directory of Rtools with seh? If not, are there relatively straightforward directions as to how to compile ICU from source for R which a neophyte can follow? Ostensibly, seh provides better performance[1], [2], and if a 4.9.2 toolchain is being developed, it may be worth considering using seh.
