Ah honestly I didn't try recently. Just looked at 
http://download.osgeo.org/osgeo4w/x86_64/release/gdal/setup.hint . If the 
build dependencies are just those ones, then it must be only the write support 
of the PDF driver which requires no dependency. For read-support, you need  
poppler for raster&vector read support, or podofo for vector read support only 
(or pdfium - new to trunk - for raster&vector read support, PDFium being 
licensed under non-copyleft terms).

Yes, trunk only anyway

Sure, building the whole stack with different compilers would require an 
automated process, and as automation doesn't work alone, people behind it.

Perhaps you meant "shipping development libraries.... for a number of compiler 
version, with/without debug symbol, etc..." ? Because at least the .h and .lib 
corresponding to the used compiler must be provided, so as to be able to build 
upper level packages.

My email was more about to try to find if the load can be shared. It shouldn't 
fall on QGIS to build the whole stack since most packages have their 
usefulness individually.

That may be a chicken&egg problem. If there are no GDAL dev builds, nobody is 
going to try them.
