Autoconf-generated configure scripts usually include the following
snippet:
ac_file_inputs=`echo $ac_file_in | \
sed -e "s%^%$ac_given_srcdir/%" -e "s%:% $ac_given_srcdir/%g"`
(This is one long line; I've split it for readability and to prevent
it from being munged by mailers.)
This makes trouble on DOS/Windows when building from another
directory. The problem is that $ac_given_srcdir may include a drive
letter with a colon after it, and the second Sed command then butchers
such names.
The remedy is to reverse the order of the two Sed commands:
ac_file_inputs=`echo $ac_file_in | \
sed -e "s%:% $ac_given_srcdir/%g" -e "s%^%$ac_given_srcdir/%"`
This should work on both Unix and DOS/Windows systems.
Please consider this change for a future release of Autoconf.
I'm sorry I cannot suggest the precise change in Autoconf files (I
don't have Autoconf installed). From what I could gather, this line
is generated as part of the AC_OUTPUT macro.
