Debian's assembler has its --version output tweaked to read
69% /usr/bin/as --version 2> /dev/null
GNU assembler 2.11.92.0.12.3 20011121 Debian/GNU Linux
[stuff]
70%
After confirming that it is GNU as in use, gcc/configure.in then runs the
top line through "sed -e 's,.* ,,'" apparently under the assumption that
the number will be the last thing printed on that line.
Under Debian, this means that the as_ver string is set to "Linux", and
then all the tests for major/minor version numbers fail.
I've changed the sed arguments to use , instead of / as a delimiter, and
moved the changequote line up a little, since this uses bracketed ranges
to grab the number string:
17% echo $asver
GNU assembler 2.11.92.0.12.3 20011121 Debian/GNU Linux
18% echo $asver | sed -e 's,[^0-9]*,,' -e 's, .*,,'
2.11.92.0.12.3
19%
This patch is against 3.0.3. It fixes the configure run under Debian
but should probably be tested on other GNU binutils-using platforms
before applying. My Red Hat boxes are production machines with no spare
computer cycles.
