The configure.ac changes look fine to me.
Thanks! That part alone ought to fix the in-tree gmp breakage.
Feel free to push that one through now since it seems like a bit of a
no-brainer.
Not sure about the Makefile.in changes, probably because I simply
don't understand this mess anymore. Is it the $INCLUDES or
$CPPFLAGS from ALL_CPPFLAGS that causes the problem? I'm guessing
the latter since it's substituted via @CPPFLAGS@.
If so, shouldn't we use BUILD_CPPFLAGS=$INCLUDES $(CPPINC)?
INCLUDES is the problem.
INCLUDES = -I. -I$(@D) -I$(srcdir) -I$(srcdir)/$(@D) \
-I$(srcdir)/../include @INCINTL@ \
$(CPPINC) $(GMPINC) $(DECNUMINC) $(BACKTRACEINC) \
$(CLOOGINC) $(ISLINC)
?!? Not sure how I missed that. Yea, and thanks for touching on ISLINC
and CLOOGINC since those were my first thoughts when I looked at this again.
Of course, then your question becomes, why exclude CPPFLAGS? (And if
CPPFLAGS needs to be excluded here, then I should have just used
CPPFLAGS=-DGENERATOR_FILE for the recursive configure call..) I'm not
sure now, I'll have to do some digging. Also as to why @INCINTL@ was
removed, when gettext is potentially needed for the gen programs.
Thanks. My inclination is to go forward with this hunk as well, with
any tweaks you find after investigating the situation around CPPFLAGS.
