Description Francois-Xavier Coudert 2008-01-04 10:35:47 UTC 
(Report initially found at http://groups.google.com/group/comp.lang.fortran/browse_frm/thread/f9d7753cad4d9708/37f0d91ea07e38a1?tvc=1#37f0d91ea07e38a1 and http://groups.google.com/group/comp.lang.fortran/browse_frm/thread/f9d7753cad4d9708/37f0d91ea07e38a1?tvc=1#37f0d91ea07e38a1)

When configured with CFLAGS=-pipe and FFLAGS=-pipe, kinds.h contains:
  #define GFC_REAL_4_HUGE f
instead of:
  #define GFC_REAL_4_HUGE 3.40282347e38f

Somehow, mk-kinds-h.sh doesn't run well when the compiler is invoked with -pipe. I haven't tested this myself, but it most probably is target-independent.

I think I understand why this happens...

        PR libfortran/34669
        * mk-kinds-h.sh: Compile with -S to avoid calling the assembler,
        to avoid piping the -fdump-parse-tree output to the assembler
        when configuring with -pipe.
        * mk-sik-inc.sh: Likewise.
        * mk-srk-inc.sh: Likewise.
