Unfortunately, I can’t get to the bottom of this at the moment.
I tried installing devkit from master on a XP VM following your
instructions, but mingw’s make segfaults. I don’t know what’s causing
it. And the machine I used to test on has been wiped, so this VM is all
I’ve got to test on right now

If you’re seeing something like below, it could be that something on the
XP system is conflicting with the DevKit’s msys-1.0.dll and the DLL
needs to be rebased [1]. We’ve recently seen an issue [2] in which an
AV vendor’s DLL collided with the DevKit’s msys-1.0.dll. The fix was a
“rebase -b 0x30000000 msys-1.0.dll” If you want to double check, the
VMMap GUI tool [3] makes it pretty simple.
HTH.
I’m on vacation for a week and will look again when I return. FYI,
looks like build.xml’s new clean-tzdata [4] target causes problems when
using msysgit’s portable version. Doesn’t look to be a showstopper and
I’ll try to get you a patch when I return. You’d think “osfamily” on
the and a windows-only would solve it, but one of the 3
ways to run msysgit portable (git-bash.bat) causes problems.
