Looking over the results of configure for a DJGPP-to-h8300 cross compiler
there appears to be an issue with the setting of the target_alias. Within
the file \gnu\gcc-2.952\build.djg\gcc\Makefile I have the following lines

# There may be a premade insn-attrtab.c for this machine.
# (You could rebuild it with genattrtab as usual, but it takes a long time.)
# PREMADE_ATTRTAB is the file name of the file to use.
# PREMADE_ATTRTAB_MD is the md file it corresponds to.
PREMADE_ATTRTAB_MD = Makefile  # Guaranteed not to cmp equal to md.
PREMADE_ATTRTAB =

target=h8300-hitachi-hms
target_alias=djgpp
xmake_file= /djgpp/gnu/gcc-2.952/gcc/config/i386/x-djgpp
tmake_file= /djgpp/gnu/gcc-2.952/gcc/config/h8300/t-h8300
/djgpp/gnu/gcc-2.952/gcc/config/t-install-cpp

So even though I specify within my configure script the target as being
h8300-hitachi-hms, the target alias is set at djgpp. This appears to be
incorrect. What further concerns me is the code to set the target alias for
djgpp (found in \gnu\gcc-2.952\config\mh-djgpp) is inlayed twice into the
above mentioned makefile; once before this output and once after.  So even
if I hand change the target alias to h8300-hitachi-hms I am not quite sure
the makefile is setting it back again?

Also why does mh-djgpp search target_alias for -pc-msdosdjgpp and not search
just target?
