Ralf,
This test succeeded in my configure. (Though I had to download and 
install the new version of autoconf. This package complained that it 
needed at least autoconf 2.59. Any idea when the new version will be 
rolled into MinGW?)

However, it didn't fix the problem with linker. It is still complaining 
about not finding things that are supposed to be in the math library. In 
fact, closer examination (CTRL-C before the first error messages scroll 
out of the buffer) shows that even things like sprintf, atoi, and atof 
are not being found. It is starting to feel like there is something in 
the Makefile that is causing the linker to ignore the standard libraries.

More info: I'm trying to build the geotiff libraries and the 
prerequisites (libtiff, proj, and jpeg). The other three packages 
compile and link with no problems. But, I've had no luck (or at least no 
*good* luck) getting the geotiff package to build. And I'm not getting 
any response at all from the geotiff mailing list.

With much snippage of duplicate lines, this is what I get when I try to 
build libgeotiff. Can anyone see any obvious problems with this?

TIA,
Thom

OBTW, my LIBDIR enviroment variable is "/usr/local/lib:/mingw/lib"
