ouch I see lots of problems on cygwin. Does not build with make -j 3 but maybe this is expected... Still make test fails for me. Some seem to be issues with file perms but the re ones seem worrisome. :/
make test output gives:
hth --steph
Failed 26 tests out of 2336, 98.89% okay.

a rebase at a fixed address should probably be done just after the build... as some dlls gave a fork error. Most tests could use a "spawn" instead of fork-exec. Please p5p give us a spawn this would be useful on cygwin. These days I maintain a rebase db for all my perls. A given dll gets the same base address. I don't use the cygwin rebase db, it does not fit my needs for many perls and a third of cpan installed ;)
