Inkscape fails to build on Window with GC errors

[jazzynico]

Reproduced on Windows XP (32bit), Inkscape trunk rev. 14557 and devlibs r32, compiling with btool.
Not reproduced with trunk rev. 14538.

Very likely a regression introduced in rev. 14543 (see http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/14543).

libgc version is 7.1.

I guess we should upgrade our win32 devlibs with GC 7.4 too.

[Alex Valavanis (valavanisalex)]

Hopefully fixed in lp:inkscape r14558. Once we've updated to gc >= 7.2 on all supported platforms, we can remove the conditional build.

Compiled successfully with GC 7.4.2 on Windows XP (32bit devlibs). More tests in progress.

Thanks for your patch, Alex!

My tests applied to rev. 14557, without the patch. I'm not sure if other recent operating systems still use GC 7.1 (Debian stable and Ubuntu LTS switched to 7.2). So I guess we can remove you patch as soon as the devlibs are updated.

GC updated (with 7.4.2) in the devlibs, rev. 54.
