Hi Karl,

libptexenc is a libtool library, treated almost like an executable. One
difference is the use of *_LIBADD vs *_LDADD.

Hi Ken,

applied (r25538).  It seems this is required for Cygwin DLLs (why not as
well for ELF shared libraries?) and it certainly does no harm.  The effect
is to record the dependency on libkpathsea in libptexenc.la and for Linux
and Co to encode this dependency in libptexenc.so.
