base: freeze-1_6_0 ./configure crashes under MinGW

[Tom Koelman]

Hi,

I checked out make & base freeze-1_6_0 and objc HEAD and tried to
build under MinGW. The ./configure of base then crashes at the point
at which it is "checking whether objc really works". base-1_5_1
doesn't crash here, so I guess it has something to do with the
following change:

Index: configure.ac
===================================================================
RCS file: /cvsroot/gnustep/gnustep/core/base/configure.ac,v
retrieving revision 1.7
retrieving revision 1.11
diff -r1.7 -r1.11

---
>   NX_CONST_STRING_OBJCFLAGS=""
450c454
< AC_SUBST(NX_CONST_STRING_CPPFLAGS)
---
> AC_SUBST(NX_CONST_STRING_OBJCFLAGS)


But I have no idea why this would cause a crash. I may have time to
investigate this later, but for now has anyone an idea?
