-Here are the libtool patches I've worked up for cygwin32 support.
-These should be relative to the 1.2 release.
-
-These patches have some bogosities.
-
-I needed to build a C file to compile when building the DLL. That C
-file naturally includes semicolons. I could not figure out how to get
-a semicolon into archive_cmds; the various approaches I tried all
-failed, because ltmain splits archive_cmds at semicolons. So I wound
-up just creating libtool.c in ltconfig. This libtool.c file never
-gets deleted.
-
-Both archive_cmds and old_archive_from_new_cmds need to use the same
-definitions file. I created it in archive_cmds and deleted it in
-old_archive_from_new_cmds.
