strlwr() is a non-standard function.
Any programs that use it will not be portable.

My guess as to why it links but won't run is that
the old (b18) cygwin.dll used to export strlwr(),
whereas cygwinb19.dll does not export it, but when
removing the function someone forgot to remove it from
the export list.

Right.

But don't call the replacement strlwr(), since names starting with str[a-z]*
are reserved for use by the implementation.  Call it say my_strlwr().
