netinet/sctp.h: present but cannot be compiled
Hello,
I'm trying to compile APR-1.2.11 on a
SunOS enpc364 5.10 Generic_120011-14 sun4u sparc SUNW,Ultra-5_10
and I'm getting the following warning I thought I should report. APR
compiles correctly though.

Seems to be OK:
---------------------------------------
configure:41928: checking whether SCTP is supported
configure:41970: gcc -o conftest -g -O2 -DSOLARIS2=10
-D_POSIX_PTHREAD_SEMANTICS
-D_REENTRANT -D_LARGEFILE64_SOURCE conftest.c -luuid -lsendfile -lrt
-lsocket
-lnsl -lpthread >&5
configure:41973: $? = 0
configure:41975: ./conftest
configure:41978: $? = 0
configure:41992: result: yes
---------------------------------------
So, I think you can safely ignore the first warning. It is caused by a
bulk test for existence of headers, which doesn't take into account
particulars of compilation requirements. My bet is that APR_CHECK_SCTP
exists precisely to remedy that.

There is a macro called APR_FLAG_HEADERS that checks various headers
(called from configure.in, defined in build/apr_common.m4), which
doesn't seem to be taking into account the fact that one may need to
have additional includes for a header to compile. So, the compilation
fails.
However, there is another macro, APR_CHECK_SCTP (defined in
build/apr_network.m4) which is called later in configure.in. Maybe we
should be calling AC_CHECK_HEADERS here instead, with correct includes
this time. Does anyone have a comment on this?
Anyhow, does that second check for SCTP work for you?

Hi Bojan,
I see the following. Perhaps I'm missing some headers ??

Can you have a look in config.log to see what actually happened at the
above points of configuration? There will be some output about what
failed exactly.
