Hi Mark,
  A short response to your 32-bit comments:

Hello Inkscape Devs,

I recently found an issue that I wanted to fix (not particularly related to this thread but it's: https://bugs.launchpad.net/inkscape/+bug/307833).

As a first time dev/user of the website/wiki/build system, I wanted to point out some issues I ran into while building Inkscape that may not be obvious to those that constantly use it. I do want to point out that overall, I think building was relatively easy.

I attempted to build under Windows 8.1 x64:

1. Bazaar seems to take awhile to download the sources, it was around 30 minutes for the 'bzr checkout lp:inkscape' command, this may be a misunderstanding of the wiki instructions and bzr though. Another 10-15 minutes was required for the devlibs64.

2. I initially tried to build a 32-bit target, however I think the compiler stated in the Wiki (GCC 4.6.1) may have been outdated for the project since there are new warnings that were turned on that I had to turn off in the build.xml for the compiler to stop complaining.

3. When building 32-bit I eventually was able to compile and link, however when copying the binaries the libgomp-1.dll appeared to be missing and the build failed - possibly due to the old compiler toolchain used from the Wiki instructions? For reference I was using: http://wiki.inkscape.org/wiki/index.php/Compiling_Inkscape_on_Windows#Setting_up_the_build_environment

Are you sure you installed TDM's GCC 4.6.1, and that that is the one that is used for building? (check the path in mingwenv.bat, and check the output of "gcc --version").
For me, the instructions on the wiki work fine. No warnings that you have to turn off in build.xml to make the build succeed. It is true that there are a ton of compiler warnings during building, but the build should succeed.

My mingw bin folder contains libgomp-1.dll, yours did not? I am not sure if I have a completely clean TDM GCC 4.6.1 install.

In any case, I recommend you work with 64-bit builds. I don't see a downside.

Hope you can find the time to improve the wiki page with your findings.

regards,
