Thanks, it's fixed now.

It is. If you compile the library without -D_REENTRANT it should leave out the
pthread-required functionality, though whether this is worthwhile is open to
debate.	It would require a system to have two DLM libraries (much as some
libraries come in  libxxx & libxxx_r flavours).

It never really bothered me (nor anyone else AFAIK), libpthread is a very small
library (included in libc on some OSs) and if you're not using the pthread
routines in libdlm never called. It would be nice if the linker could spot
this, but the overhead is largely one of typing really.

Anyone else have any strong opinions on this ?
