The change to the C preprocessor to recognize "df", "dd", and "dl" as suffixes
for decimal floating point constants also allows "fd" and "ld"; a check for
that assumed that the the letters are examined from left to right, but they are
examined from right to left. There are no errors for the following:
double a = 1.ld;
double b = 1.fd;
I'm testing a fix, but wanted a PR to reference for a patch to the 4.2 branch.
