Patch for DMD (svn r490)
This assertion fails with DMD built on FreeBSD 8:
--------------------
static assert(1.0L == 0x1.0p+0L);
// Error: static assert (0x1.00000000000004p+0L == 1L) is false
--------------------
The left decimal floating-point literal is slightly wrong.
The compiler uses some tables (negtab and postab) for converting decimal
strings to long double values, but GCC on FreeBSD/i386 slightly changes them by
rounding everything in the table to double precision. This causes precision
loss of decimal floating-point literals.
The attached patch fixes the problem, by adding byte sequence version of the
numeric tables to backend/strtold.c so that the tables' contents will not be
rounded by GCC.
