[ptx] Compiling vigra on Windows with MinGW

[Yili Zhao]

Hi,
  using google, I obtain sourcecode of zlib-1.1.4, libpng-1.2.5,
tiff-v3.6.0 and jpeg-6b, and I compile them using MinGW and get
the *.a libraries.
  I compile vigra with zlib, png, tiff, jpeg and fftw support 
successfully using MinGW and MSYS. However, when I compile vigra
exapmles, there are some errors:
  $ make examples
  make[1]: Entering directory `/d/vigra1.2.0/src'
  make[2]: Entering directory `/d/vigra1.2.0/src/examples'

  I do not know why this occur.
  Alexandre, do you use visual studio.net? I think vs6.0 has some problems with template.
If you use vs.net, how you use image library? By compiling them also with vs.net or only download compiled
library? Maybe I need to install vs.net.
