Created an attachment (id=629)
Patch for DMD (svn r487)

This code fails with dmd built on FreeBSD/i386:
--------------------
static assert(real.max < real.infinity); // fails on FreeBSD
--------------------
Some static assertions in std.math are blocked by this problem.

There is a bug in GCC on FreeBSD/i386 and long double constants are rounded to double precision(*).  A workaround is already there in DMD as Port::ldbl_max, but it seems it's forgotten. :)  The attached patch enables this workaround, and adds necessary fpsetprec.

[*] freebsd-standards: long double broken on i386? http://groups.google.co.jp/group/lucky.freebsd.standards/browse_thread/thread/5d7b42dac8d29461
