I did not know before (as the former pattern had too many wildcards).
Found out now gfortran-4.1 had the types really named like `int4'.
The excessive spacing from f-typeprint.c is a regression by:

This patch fixes it back:
(gdb) ptype q
type = Type foo
real(kind=4) :: a
Type bar
integer(kind=4) :: c
real(kind=4) :: d
->
(gdb) ptype q
type = Type foo
real(kind=4) :: a
Type bar
integer(kind=4) :: c
real(kind=4) :: d

Fedora gcc-gfortran-4.1.2-33.x86_64. Did not test upstream gfortran-4.1.
No regressions on gcc-4.3.2-7.x86_64 and no regressions for gdb.fortran/ on
gcc-4.1.2-33.x86_64. OK to commit?

* f-typeprint.c (f_type_print_base <TYPE_CODE_STRUCT>): Fix output
spacing, a regression from 2008-04-22.
gdb/testsuite/
2009-01-06 Jan Kratochvil <jan.kratochvil@redhat.com>
* gdb.fortran/derived-type.exp: New variables int4 and real4. Match
now the output exactly, using less wildcards. Expect also the output
of gfortran-4.3. Update for the f-valprint.c modification from
2008-04-22.
