And maybe for performance improvement we should transform

if ((m > 0.0 && m < 0.1 - 0.1 * r * rexp_d) || (rexp_d * (m + r) >= 1.0) ||\
   ((m == 0.0) && !(compile_options.allow_std & GFC_STD_F2003)))\

to:

if (m > 0.0 && ((m < 0.1 - 0.1 * r * rexp_d) || (rexp_d * (m + r) >= 1.0)) ||\
   ((m == 0.0) && !(compile_options.allow_std & GFC_STD_F2003)))\

for m == 0.0 this avoids evaluation of (rexp_d * (m + r) >= 1.0)) which is then
always false anyway.
