Hi Daniel,

Relative to this commit
http://curl.haxx.se/cvs.cgi/curl/m4/curl-reentrant.m4?r1=1.3&r2=1.4

Previous to that commit libcurl's and c-ares configure scripts already
detected that HP-UX needed to define _REENTRANT to be able tu use the
reentrant functions and defined it, as it can be verified on curl's
daily builds done on HP-UX since august 2008 prior to this commit.

I suppose that the initiative to 'fix' libcurl's detection comes from
a bug report on the libssh2 project which did not detect this need for
HP-UX on that project due to not using all the detection logic that
libcurl's and c-ares configure scripts have.

The libssh2 configure script is missing the
CURL_CHECK_NEED_REENTRANT_FUNCTIONS_R macro which will make that
project's configure script not detect the need for the _REENTRANT
definition on any other system that needs it besides the now two
hard-coded ones.

PS: The referred commit mail got through. The one for CHANGES 1.1746 and
m4/curl-reentrant.m4 1.4 not yet
