Hi all,
While compiling GNU Screen sources on HP-UX operating system I faced two issues:
- configure script failed to locate termcap shared libraries;
- GCC produced a batch of warnings about "incompatible implicit declaration" of
strlen and (less frequent) strcpy functions.
It's interesting for me that all these warnings seem to be intended -- there's
even special #ifdef to generate them, but for what reason? Maybe the answer is
changes in HP-UX system headers since "os.h" header has been written, but I
don't know exactly.
I'm providing a fix for all this. The following patch is tested on HP-UX on
both IA64 (OS v11.23) and PA-RISC (OS v11.11) architectures with GNU Screen
4.0.3 and works good.
