On 2006/03/28 15:55:52 +0 you committed `configure.ac' change that breaks "FOR_MSW" xpm check. Code that previously would compile and link normally now does not even compile. Replacement of `AC_TRY_LINK' with `AC_LINK_IFELSE' is incorrect, perhaps partly due to incorrect `AC_TRY_LINK' description in autoconf documentation. (However, `AC_LANG_SOURCE' is described correctly.) That change also introduced the same incorrect uses of AC_LANG_SOURCE([void *x = alloca(4);]) as entire `AC_TRY_LINK' argument. Please fix.
