for grins, and since i'll eventually need an up-to-date libcurl for
netperf work, I tried to compile the 7.10.4-pre3 bits on an HP-UX 11.11
system with the HP ANSI C compiler installed.

First, the if_ether.h error appears to stem from not also including
net/if_arp.h to get the definition of a struct arphdr, as which ea_hdr
in netinet/if_ether is declared.

configure:14065: checking netinet/if_ether.h usability
configure:14078: cc -c -g conftest.c >&5
cc: "/usr/include/netinet/if_ether.h", line 126: error 1574: Unknown
size for "ea_hdr".
cc: "/usr/include/netinet/if_ether.h", line 126: error 1578: Size of
struct or union member is unknown.
cc: "/usr/include/netinet/if_ether.h", line 157: error 1574: Unknown
size for "ea_hdr".
cc: "/usr/include/netinet/if_ether.h", line 157: error 1578: Size of
struct or union member is unknown.
configure:14081: $? = 1

$ find /usr/include -exec grep -l arphdr {} \;
/usr/include/net/if_arp.h
/usr/include/netinet/if_ether.h

It looks like the if_ether.h checks are in a loop with a bunch of
others. It may be necessary to break if_ether.h out into its own test
and perhaps have an #ifdef __hpux #include <net/if_arp.h> #endif added.

As for gettimeofday:

configure:14905: cc -o conftest -g conftest.c >&5
cc: "configure", line 14939: error 1584: Inconsistent type declaration:
"gettimeofday".

for !=.configure:14908: $? = 1
configure: failed program was:

I extracted the program from the log (very nice that the whole thing is
there, makes life much easier, but would be easier still without the
leading "| " :)

  return 0;
}

and commented-out the line directive. Seems the HP compiler is grumpy
with:

char gettimeofday ();

If I comment that out, the compiler only warns about types:

$ cc foo.c
cc: "foo.c", line 87: warning 604: Pointers are not
assignment-compatible.
cc: "foo.c", line 95: warning 605: Illegal pointer combination for !=.
/usr/ccs/bin/ld: (Warning) At least one PA 2.0 object file (foo.o) was
detected. The linked output may not run on a PA 1.x system.

If instead, I remove the include of limits.h, the test code compiles fat
dumb and happy. From that I guess that the include of limits.h ends-up
including a file that gives a definition of gettimeofday() - and of
course the redeclaration of gettimeofday as a char makes it rather
grumpy.

the issue with select appears to be the same:

-configure:14905: cc -o conftest -g conftest.c >&5
cc: "configure", line 14933: error 1584: Inconsistent type declaration:
"select".
cc: "configure", line 14940: warning 604: Pointers are not
assignment-compatible.
cc: "configure", line 14949: warning 605: Illegal pointer combination
for !=.configure:14908: $? = 1

This also happens for strftime.

So, it seems to be an autoconf vs HP-UX includes issue?
