Hi Thimo,

Thanks for the feedback -- much appreciated.

If I wrote 'one call' , I probably meant 'one function'. Sorry.

This is swig-generated code from a __large__ c++ project that takes more than
an hour to build on my reasonably beefy x86 box with 2gb ram.  It may not be
appropriate for mips/mipsel.

Yup. See above.

Could we possibly have a discussion on whether we should exclude the three
related packages

	quantlib
	quantlib-swig
	rquantlib

from building on mips/mipsel and arm?  They are already excluded on m68k (but
then m68k is sort-of a moot point anyway).

Please don't misunderstand my point of view. I like mips. I think I'll get a
'slug' box, and I run a linksys router.  It's just that QuantLib is really
meant for decent-size workstations. 

Thanks for the feedback,  Dirk
