I think just ignore (..) . It seems to add no value at this time and assures
compatibility across platforms. Your patch is OK.

- convert_real needs to get the comment updated (assuming POSIX/C99 strtod)
I think that's the only item left to do: Deleting the following TODO from
read.c's convert_real - and then the

Tobias,
Your patch is approved. Also, I managed to get all your comments addressd for
the read_f patch including signs on Inf last night and will resubmit tonight.

Actually, in list_read.c's parse_real gfortran already handles inf(inity) and
nan (_but_ _not _nan(string)). Thus, using 'read(*,*) a' works.

The TODO quote from comment 2 is for read.c's convert_real;

program should be: (both exhibit the bug though, but this works if bug is not
present)
program nan_test
implicit none
character(15) :: nan = ' NAN -INF INF'
real :: a,b,c, d = 0.0

Confirmed. In io/read.c we have:
/* TODO: handle not-a-numbers and infinities. */
I will take this on. But it is back burner to some other issues.

(1) On input, leading blanks are not significant. When the input field is not
an IEEE exceptional specification (10.6.1.2.1), the
