That's what I tried before, but it does not help.
If I clone with: git clone https://git.savannah.gnu.org/git/libtool.git
I get different line numbers:
% git diff

Am I on the right branch?
With that patch I get in share/aclocal/libtool.m4

However, this does not help.
I still get in my project libtool:
# A language specific compiler.
CC="ftn"
# Is the compiler the GNU compiler?
with_gcc=no
# Compiler flag to turn off builtin functions.
no_builtin_flag=""
# Additional compiler flags for building library objects.
pic_flag=""
# How to pass a linker flag through the compiler.
wl=""
I wonder if flang/ftn is applied in the right place in m4/libtool.m4.
Or maybe has to be applied in several places.
Other compilers appear multiple times, e.g. nagfor:
% grep -nC1 icc m4/libtool.m4
4714- ;;
4715: # icc used to be incompatible with GCC.
4716- # ICC 10 doesn't accept -KPIC any more.
4717: icc* | ifort*)
4718- _LT_TAGVAR(lt_prog_compiler_wl, $1)='-Wl,'

5217- tmp_addflag=' $pic_flag -Mnomain' ;;
5218: ecc*,ia64* | icc*,ia64*) # Intel C compiler on ia64

ashterenli@NB-068 libtool % grep -nC1 nagfor m4/libtool.m4

or ifort:
