Your search of the JPEG header files is broken under MSYS because you use the $includedir variable as is. Unfortunately that variable includes a variable which needs to be evalutated. (i.e. it is not the result of "${prefix}/include"; it is '${prefix}/include' as such!) You can look at your configure script and search for includedir= I have a patch for the m4/libjpeg.m4 file. Thank you, Alexis P.S. would is be possible for you to add the available versions in Bugzilla? So that way we can see when a bug was logged what version it was for. Thanks!
Created attachment 7871 [details] [review] Fix for the JPEG search m4 script so it works under MSYS "$includedir ..." becomes: "`eval echo $includedir` ..." And it works 8-)
fixed thanks
