I've run the testsuite of libtool on a Cygwin 1.5.25 on WinXP (no Fortran compiler installed), with the patch series posted here applied: Since I only have remote access to this windows system, and since the libtool testsuite is very slow on Cygwin, I've used the following command run to build and test libtool, so the the testsuite could continue to run without me having to remain logged in the whole time: $ (nohup sh -c './configure && make && make check') & Attached are the generated output (nohup.out), and the `config.log' and `tests/testsuite.log' files.
