This backports the relevant bit of svn revision 1177 to fix build on platforms
where long double does not have extended range (larger than regular double),
particularly PowerPC (32 and 64 bit).
On those platforms, the build previously failed with:
Tokenizer.cc:769:4: error: floating constant exceeds range of 'long double' [-Werror=overflow]
exp_0_9(1E30)
