The sed command that gives the error is:

  -e 's;\(#.*PATH_SITELOADSEARCH\).*$$;\1 "'"$${w32locallisppath//;/\\;}"'";'

There is an unquoted ; in the replacement, but quoting that does not fix
the error.

I'm guessing the reference to 'w32locallisppath' is supposed to replace
the Unix path separator : with the Windows path separator ; . But the
shell syntax for that would be:

${w32locallisppath/:/;}

The escaped make syntax would then be:

$${w32locallisppath/:/\\;}

but that doesn't fix the error either. And 'msys-to-w32' has already
done that substitution, so doing it here is wrong.

I could not find a variation that fixes the error.


'git blame' says this line was last edited in 2014:

's;\(#.*PATH_SITELOADSEARCH\).*$$;\1 "'"$${w32locallisppath//;/\\;}"'";' \

so this has apparently been working for a long time; I don't understand
why it's failing for me now.


I don't specify --enable-locallisppath, so I can work around this by
simply deleting that line from Makefile.in. That lets configure complete.
