I can now build the parallel package against the default branch with this change, closing as fixed.

I think the sighnalders.h file is fixed now so that it doesn't include the signal-wrappers.h file.

Thanks for pointing out this issue.

Cleaning up the public interfaces is still a work in progress.

I'll try to take a look at this soon.

Confirmed. Agree that it is not a bug in 'parallel', but in Octave.

'parallel' uses 'octave_child_list' and so has to include sighandlers.h. But any external code that includes this file currently won't work.

The parallel-3.1.0 package fails to build with the current
development octave-4.1.0+. signal-wrappers.h is not found:

$ /usr/local/dbg-octave/bin/octave-cli --eval 'pkg install parallel-3.1.0.tar.gz'
configure: WARNING: TLS disabled since symbol gnutls_srp_2048_group_prime not found in gnutls library - built with --disable-srp-authentication?
In file included from pserver.cc:28:0:
/usr/local/dbg-octave/include/octave-4.1.0+/octave/../octave/sighandlers.h:38:29: fatal error: signal-wrappers.h: No such file or directory
 #include "signal-wrappers.h"
compilation terminated.
make: *** [pserver.o] Error 1

sighandlers.h is installed in include/octave-4.1.0+/octave but signal-wrappers.h is not. The liboctave/wrappers directory is not present in the octave-4.0.2 sources. If the current source is present then a workaround is to give the include path to the source file explicitly. In my case:

Perhaps this is not a bug in the "Octave Forge Package" category but belongs in "Configuration and Build System"?
