Hello.

Got this output:

/usr/bin/ld: /tmp/ccAhUuiW.o: @gprel relocation against dynamic symbol x
collect2: ld returned 1 exit status

and so as you would expect:

$ gcc conftest.c -ldl
$ ./a.out
$ echo $?
2

But ...

as per this suggestion:

gcc -shared  -fPIC conftest_dl.c -o conftest_dl.so
bash-2.05a$ ./a.out
bash-2.05a$ echo $?
3

however...

I tried this, and got this output during configure:

checking if '/LD' builds loadable libraries...
checking if '/LD /ML /nologo' builds loadable libraries...
checking if '-shared' builds loadable libraries...
checking if '-shared -fPIC' builds loadable libraries...
checking if '-bundle' builds loadable libraries...
checking if '-bundle -lc' builds loadable libraries...
checking if '-r' builds loadable libraries...
...
creating ../config.h
...

Leaving config.h with:

#define MKDLL_CMD "gcc "

and the predictable build failure:

...../ffihugs -N +G -W +L"../lib/exts/Storable_aux.c" HugsStorable
/usr/lib/crt1.o: In function `_start':
/usr/lib/crt1.o(.text+0x41): undefined reference to `main'
