commit b7db2842666286bb66111b1da46e707bf5d417b4
Author: Daniel Stenberg <address@hidden>

    configure: set PATH_SEPARATOR to colon for PATH w/o separator
    
    The logic tries to figure out what the path separator in the $PATH
    variable is, but if there's only one directory in the $PATH it
    fails. This change make configure *guess* on colon instead of erroring
    out, simply because that is probably the more common character.
    
    PATH_SEPARATOR can always be set by the user to override the guessing.
    
    (tricky bug to reproduce, as in my case for example the configure script
    requires binaries in more than one directory so passing in a PATH with a
    single dir fails.)
    
    Reported-by: Earnestly on github
    Fixes #2202
    Closes #2265
