Agreed.  Well-behaved configure scripts should use what they get
from autoconf, and not by running uname themselves.  And autoconf
takes its settings from the command line, falling back on
config.guess (which calls uname to detect DJGPP).

In fact, I think simply updating the package's config.guess should be
enough; the config.guess in my automake CVS tree (not updated in a
month or two has:


UNAME_MACHINE=`(uname -m) 2>/dev/null` || UNAME_MACHINE=unknown
UNAME_RELEASE=`(uname -r) 2>/dev/null` || UNAME_RELEASE=unknown
UNAME_SYSTEM=`(uname -s) 2>/dev/null`  || UNAME_SYSTEM=unknown
UNAME_VERSION=`(uname -v) 2>/dev/null` || UNAME_VERSION=unknown

# Note: order is significant - the case branches are not exclusive.

case
"${UNAME_MACHINE}:${UNAME_SYSTEM}:${UNAME_RELEASE}:${UNAME_VERSION}" in
[snip]
    i*86:*DOS:*:*)
        echo ${UNAME_MACHINE}-pc-msdosdjgpp
        exit 0 ;;
    pc:*:*:*)
        # Left here for compatibility:
        # uname -m prints for DJGPP always 'pc', but it prints nothing
about
        # the processor, so we play safe by assuming i386.
        echo i386-pc-msdosdjgpp
        exit 0 ;;
[snip]


So it would seem to support both types of uname.
