I've been working on a resurrection patch for Interix, one remaining problem is fixincludes/fixincl.c must be compiled on native Interix with -D_ALL_SOURCE in order to find the getpagesize prototype.
This works (taking some liberties with diff...): fixincludes/Makefile.in -FIXINC_CFLAGS = -DHAVE_CONFIG_H $(INCLUDES) +FIXINC_CFLAGS = -DHAVE_CONFIG_H $(INCLUDES) -D_ALL_SOURCE Obviously unacceptable in general. Fixincludes ignores a config/mh-interix, so adding FIXINC_CFLAGS += -D_ALL_SOURCE doesn't work. What is the correct solution? Any advice would be greatly appreciated.
