Thanks a lot for the hint!
The thing is, while it does compile now, I'm not sure it's correct.

These are the relevant files in libgomp/.libs:
-rwxr-xr-x 1 root root 262318 Jul 10 18:54 libgomp-1.dll
lrwxrwxrwx 1 root root     13 Jul 10 18:54 libgomp.dll.a -> libgomp-1.dll
lrwxrwxrwx 1 root root     13 Jul 10 18:54 libgomp.la -> ../libgomp.la
-rw-r--r-- 1 root root   1124 Jul 10 18:54 libgomp.lai
-rw-r--r-- 1 root root 284660 Jul 10 18:54 libgomp.lib

libgomp.la still says
# The name of the static archive.
old_library='libgomp.lib'

The .lib file seems to be a static library. There's no import library
anywhere.

The sibling directory, libssp, seems to have everything correct:
-rwxr-xr-x 1 root root 39408 Jul 10 18:54 libssp-0.dll
-rw-r--r-- 1 root root 33196 Jul 10 18:54 libssp.a
-rw-r--r-- 1 root root  8114 Jul 10 18:54 libssp.dll.a
lrwxrwxrwx 1 root root    12 Jul 10 18:54 libssp.la -> ../libssp.la
-rw-r--r-- 1 root root  1093 Jul 10 18:54 libssp.lai
-rw-r--r-- 1 root root  1996 Jul 10 16:56 libssp_nonshared.a
lrwxrwxrwx 1 root root    22 Jul 10 16:56 libssp_nonshared.la -> ../libssp_nonshared.la
-rw-r--r-- 1 root root  1092 Jul 10 16:56 libssp_nonshared.lai


I copied the libtool file from libssp to libgomp, and now the
files seem to be correct:
-rwxr-xr-x 1 root root 262318 Jul 10 19:10 libgomp-1.dll
-rw-r--r-- 1 root root 284660 Jul 10 19:10 libgomp.a
-rw-r--r-- 1 root root 143514 Jul 10 19:10 libgomp.dll.a
lrwxrwxrwx 1 root root     13 Jul 10 19:10 libgomp.la -> ../libgomp.la
-rw-r--r-- 1 root root   1108 Jul 10 19:10 libgomp.lai

So, is this the right way to proceed?
I'm also interested in patching the original gcc source tree
(as opposed to build tree), because I'm actually trying to build
an rpm package.


Thanks a lot,
Alexander
