I skimmed the patch. It is still wrong.
These parts should not be needed:
+ if (!saw_r8)
+ fatal_error ("real kind=8 not available for -freal-4-real-8 option");
+ if (!saw_r4)
+ fatal_error ("real kind=4 not available for -freal-8-real-4 option");
gfortran always has real(4) and real(8) on all important targets.
I also think that the description is the manual is lacking. For example,
+freal-4-real-8
+Fortran RejectNegative
+Interpret any 4-byte real as an 8-byte real
I think the word 'any' is incorrect.
There also should be a warning here. "Warning: This option is provided
for debugging purposes, and may give unexpected results for general
use."
