Mac OS installation problem

[Jean ABOU SAMRA]

Hi there,
I'm trying to install Guile 1.8 (_not_ the latest 2.2.6 version) on Mac OS 
10.14 Mojave. I downloaded the guile-1.8.8.tar.gz file from 
ftp://ftp.gnu.org/gnu/guile/ <ftp://ftp.gnu.org/gnu/guile/> . However, after 
running ./configure, running 'make' stops with the following error:

gc-malloc.c:95:20: error: comparison of unsigned expression < 0 is always false 
[-Werror,-Wtautological-compare]
  if (scm_mtrigger < 0)


Then I realised that the `gcc` command was pointing to clang (as by default on 
Mac OS) so I installed GCC 9.1.0 and forced the `gcc` command to point to this 
GCC. When I extracted the archive again in a new folder and executed 
./configure, I ran into another problem:

checking whether we are cross compiling... configure: error: in 
`/Users/jean/Applications/guile-1.8.8-new':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details


I attach the logs generated by the compilation commands:

iMac:guile-1.8.8 jean$ # This is with clang.
iMac:guile-1.8.8 jean$ ./configure
iMac:guile-1.8.8 jean$ make &> guile-make.log # attaching 'guile-make.log'

iMac-devoirs:guile-1.8.8-new jean$ # This is with GCC 9.1.0.
iMac-devoirs:guile-1.8.8-new jean$ ./configure # attaching 'config.log'


Any hints on how to get Guile to compile?

Thanks in advance,
Jean Abou Samra.
