More odd behaviour of gm2 on Solaris 11.3/Sparc

[john o goyo]

Greetings, Gaius.

Here are the latest oddities.

(0) I built and installed gm2 from the git repo of (partial) hash 
55ca43c..806751e without incident.  Here is my configuration script.

NM=/usr/bin/gnm \
SHELL=/usr/bin/bash \
AR=/usr/bin/ar \
AS=/usr/bin/as \
CC=/home/build/gcc/12.2.0/bin/gcc \
CXX=/home/build/gcc/12.2.0/bin/g++ \
../../src/gcc-git/configure \
--prefix=$HOME/gm2/git \
--exec-prefix=$HOME/gm2/git \
--enable-languages=c,c++,m2 \
--disable-plugin \
--with-mpc=/usr/local \
--with-gmp=/usr/local \
--with-mpfr=/usr/local \
--enable-threads=posix

(1) I tried to compile+link a C programme as a sanity check.

[~/prj/tst]=> cat what.c
#include <stdio.h>

int
main(void)
{
    puts("What?!");
    return 0;
}
[~/prj/tst]=> /home/build/gm2/git/bin/gcc -O2 what.c
[~/prj/tst]=> ll a.out
-rwxr-xr-x   1 build    staff       6916 Dec  2 17:30 a.out
[~/prj/tst]=> ./a.out
What?!

(2) I tried to compile+link a Modula-2 programme.

[~/prj/tst]=> cat first.mod
MODULE first;

   FROM InOut IMPORT WriteString, WriteLn;

BEGIN
   WriteString("Modula-2. What else?"); WriteLn;
END first.
[~/prj/tst]=> cat first.mod
MODULE first;

   FROM InOut IMPORT WriteString, WriteLn;

BEGIN
   WriteString("Modula-2. What else?"); WriteLn;
END first.
[~/prj/tst]=> /home/build/gm2/git/bin/gm2 first.mod
[~/prj/tst]=> ll a.out
-rwxr-xr-x   1 build    staff     512672 Dec  2 17:33 a.out
[~/prj/tst]=> ./a.out
Modula-2. What else?

(3) Added some environment.

[~/prj/tst]=> env

/home/build/gm2/git/bin/gm2 -L/home/build/gm2/git/lib first.mod -lsocket

ld: fatal: symbol referencing errors
collect2: error: ld returned 1 exit status


Question: Is there some way of specifying where gm2 should look for its 
libraries?

Sincerely,
