netcat-openbsd/glib-strlcpy.patch
OBS User mrdocs 866517e65e Accepting request 214314 from home:elvigia:branches:network:utilities
- drop dependency on glib, strlcpy can be implemented with 
  snprintf with glibc/linux
- drop "quilt" from buildrequires, no longer used.
- Use fvisibiliy=hidden to build, this is a program not
  a library and no symbols should be exported.
- modified patches:
  * glib-strlcpy.patch
