No, this is not correct. My original email exactly described the
problem: when linking the libsrfi-1 library with libtool 1.5.10 on
Cygwin, libguile.dll.a is not linked, causing the link to fail.

For mysterious reasons (libtool brokenness, I suppose), the compile
and make install do continue, but at run-time the (use-modules .. )
call throws error 126, which is entirely understandable, since
/usr/lib/ does not contain the libsrfi-1 DLL.

When linking libsrfi-1 by hand (inserting libguile.dll.a into the
command line),  and copying the resulting DLL to /usr/lib/ , use-modules
works correctly.
