Reduced test

#if plet=='s'
#define ckind
#endif
end

[Book15] f90/bug% gfc -cpp pr65025_db_1.f90
built-in: internal compiler error: Segmentation fault: 11

I see it with gfortran 4.4.7.

The small test program that shows the error.

Maybe this time the code will get there?

The code was there in this PR, but not in 65026.

#if plet_=='s'
#define ckind__ C_FLOAT
#elif plet_=='q'
#define ckind__ C_LONG_DOUBLE  
#elif plet_=='d'
#define  ckind__ C_DOUBLE
#endif
end

is enough to reproduce the ICE.

In collapsing a big code to the small example, I left out a line that should be
there.  Add below the first line

  use ISO_C_BINDING, only: C_DOUBLE, C_FLOAT, C_LONG_DOUBLE

This has no effect however on the internal compiler error.

I realize (now) that this is not a valid Fortran code.  I was trying to hard to
make it work like it works in C.  Removing the apostrophes around the s, d, and
q, in both the code and on the command line, and all works, although I'm not
sure about it being portable.
