To be honest I don't understand that error, those aren't the usual undefined
references you would expect - you are clearly linking to the regex library
OK, but are getting undefined references to *inline* functions from the
regex headers.  Are there any g++ options that effect this?  Did you do
anything different/unusual when you built the library?
