It seems that this version of pthreads assumes that DJGPP doesn't have
the `sigpending' function and provides its own version.  This
assumption is no longer true: DJGPP v2.01 has `sigpending' in its
library, and therefore the linker complains about double definition.
(The linker cannot avoid linking in `sigpending' because it is defined
on the same module as `sigprocmask'.)

A solution would be to define away the version that pthreads uses for
DJGPP.  (Or maybe there is a version of pthreads which is compatible
with DJGPP v2.01.)
