[Quantlib-dev] 0.3.11 fails to compile under newest g++-4.0

[Dirk E. <ed...@de...>]

QuantLib'ers,

I was updating the Debian packages of 0.3.11 ( for a C++ transition we're
undergoing relative to to libstd++ and the standard allocation, details at
http://article.gmane.org/gmane.linux.debian.devel.announce/763 ), and I ran
into

It turns out that the suggested '-fpermissive' fixes it. From my build-logs,
it worked fine without it on Oct 21 with the then-current g++-4.0 (4.0.2-2,
judging from its changelog). The current one is 4.0.2-4 with the changed
allocator, and something must have changed along with it.

But then given the speed with which things move around here, it probably has
long been updated in CVS anyway :)

Cheers, Dirk
