All jpeglib versions from 7 to 9 are binary incompatible with earlier
ones.

The naming scheme of the libpng library on w32 is either libpngXY.dll
or libpngXY-XY.dll where X being the major version, Y the minor
version number, respectively.

Comments in NetPBM headers can occur in the middle of a token.

I installed this with minor changes:
. renamed jpeglib-version to libjpeg-version, for consistency with
other image libraries;
. changed the comparison in w32-win.el to compare against 62, not 0,
because jpeg6 does define JPEG_LIB_VERSION; the comparison says
now
(if (> libjpeg-version 62)
. added a comment in w32-win.el explaining the reasons for the binary
incompatibilities
