Thomas Koenig 9a0fb43ea1 re PR fortran/26769 (Implement transpose() and reshape() for real instead of using integer)
2006-03-25  Thomas Koenig  <Thomas.Koenig@online.de>

	PR fortran/26769
	* iresolve.c (gfc_resolve_reshape):  Remove doubling of
	kind for complex. For real(kind=10), call reshape_r10.
	(gfc_resolve_transpose):  For real(kind=10), call
	transpose_r10.

2006-03-25  Thomas Koenig  <Thomas.Koenig@online.de>

	PR fortran/26769
	* Makefile.am:  Add transpose_r10.c and reshape_r10.c.
	* aclocal.m4:  Regenerate using aclocal 1.9.3.
	* Makefile.in:  Regenerate using automake 1.9.3.
	* m4/iparm.m4 (rtype_ccode):  If rtype_letter is `i',
	evaluate to rtype_kind, otherwise to rtype_code.
	* generated/transpose_r10.c:  Add.
	* generated/reshape_r10.c:  Add.

2006-03-25  Thomas Koenig  <Thomas.Koenig@online.de>

	PR fortran/26769
	* gfortran.dg/transpose_reshape_r10.f90:  New test case.
