I agree. However, this doesn't work in all cases. For example, while
playing around with modifications for hppa64*, I ran into a case where
a program was built with:
$CC $pic_flag -DPIC [program]
I think it had to do with -dlpreopen (double checking, run
pdemo-make.test in HEAD and you'll see the problem:
$ cd tests
$ sh pdemo-make.conf
...
rm -f .libs/helldl.nm .libs/helldl.nmS .libs/helldl.nmT
creating .libs/helldlS.c
extracting global C symbols from `./.libs/libhello.a'
(cd .libs && cc -c "helldlS.c")
rm -f .libs/helldlS.c .libs/helldl.nm .libs/helldl.nmS
.libs/helldl.nmT
cc -mr -Qn -xstrconst -xO2 -xtarget=generic -xarch=v8 -o .libs/helldl
.libs/helldlS.o longer_file_name_dlmain.o ./.libs/libhello.so -lm
-R/opt/build/libtool-1.5/tests/_inst/lib
creating helldl
Because libtool knows nothing about $CFLAGS, it's not possible for it
to know about the appropriate switch (+DD64 in this case) to build
64-bit object files. Even though the answer was in $CFLAGS, libtool
doesn't get passed $CFLAGS. My solution was CC="cc +DD64".
So, do we teach libtool to inherit $CFLAGS?
