There were many posts, but none of them had such a misleading subject yet ;)[For me "are no longer readable" sounds like a much more serious problem than just some size mismatch.]

even if there would be a font-config based build it wont solve the problem which is (part of, but also read below) :
_different fonts_ provide by any system will generate different sized bounding boxes. There is no magic in Pango or font-config to resolve this issue long time known in Dia land. Note: this is not a matter of the platform you are running Dia on but a matter of concrete font files. Ensure they are the same, and appropriately mapped/named in you font configuation and the problem is gone.
By default Dia currently uses very weak hints to the font system which font to use, like 'sans', 'serif', 'monospace' - that is : the first font in the systems enumeration which is classified as being of the respective type. Depending on your system for e.g. sans-serif this may be :
'Helvetica - on common Linux (if there is such) 'Luxi Sans' - with osx/X11 'Arial' - with win32 (either Pango/FT2 or Pango/win32 based)

you should be able to reduce (if not eliminate) the issue by having the same font files installed on both systems _and_ explicit select the desired font in Dias font properties.

You can Ctrl+A to select all, and then just move it back and forth a bit, that should resolve most of it. It is, however, a problematic issue. Problem is that Win32 and Pango don't agree on how to render fonts, so they have slightly different widths, which in turn determines the size of the boxes. Haven't found a good solution yet.
Sorry Lars - but I've a different understanding of the problem. I've tried Dia on win32 with both backends Pango/win32 and default font-config/Pango/FT2 and beside marginal different aliasing the sizes were exactly the same. Also aren't you comparing apples to elephants (Pango and Win32)? Shouldn't that read FT2 and win32 font rendering ? Or did you mean font-configs font list compared to the one provided by win32::EnumFontFamilies() ?
UPDATE: Repeating my test with 0.93 (they were originally done some month ago with some 0.92 or even 0.91 ?) did show a IMO serious regression though. Font sizes between the backends are no longer the same. To test yourself try the attached UML-Test (original from Dias distribution, I've put in an additional layer showing the UML Class box sizes with Dia-0.90-win32. Loading the file with 0.93(Pango/win32) shows some small deviation, some few percent as expected. But loading the same file into .93(Pango/FT2) shows that the boxes - and thus the reported text length - are about 30% smaller. To me this looks like an unacceptable regression - I simply have too much diagrams done with 0.90 ...
Confused (-;
