I'm not using a BSD system.  I only quoted where the function was
originating from.

The error for me showed up when building a cross compiler to a
glibc-based system.  I will try to investigate why the libiberty
configure machinery failed to detect the `psignal' symbol from the
target's glibc, which should have included that symbol.  The error showed
up, because the target glibc's <signal.h> header had been included and
thus its `psignal' declaration didn't match the libiberty `psignal'
definition.


Nevertheless, I don't understand why you don't want to adapt the
parameters to what other systems (glibc, BSD) are using?  Why should
libiberty provide a (marginally) different version of `psignal'?
