PCRE is distributed under a three-clause BSD license, and so should be compatible on that account. Most Linux systems (at least) should have the library installed, as many, many programs use it. Re libtool support, PCRE's build system has been using it for some time, but only recently to the extent of installing the *.la files.

Sounds reasonable. (Although you'd probably get a lot of mileage adding optional PCRE support directly into gnulib....) Adding the necessary hooks looks like a non-trivial task, however (esp. as far as making the set of available RE syntaxes dynamic), so that'll probably have to wait for everyone's undivided attention. --Daniel -- NAME = Daniel Richard G. ## Remember, skunks _\|/_ meef?
