The configure test for AIX is producing a false positive.
This is resulting in the _ALL_SOURCE macro being defined.
As near as I can tell, I do not see any bad effects on VMS.
It looks like the problem is that the test should produce a compile
failure to indicate AIX, and instead a compile success is being used.
Not quite. The code for CURL_CHECK_AIX_ALL_SOURCE in acinclude.m4 does
this:
AC_EGREP_CPP([yes_this_is_aix],[
#ifdef _AIX
yes_this_is_aix
#endif
],[
AC_MSG_RESULT([yes])
AC_DEFINE(_ALL_SOURCE)
],[
AC_MSG_RESULT([no])
])
Which means it'll preprocess that little snippet of code and check for
'yes_this_is_aix' in the output. That should only happen if _AIX is
defined when the preprocessor runs... Or can you think of any other
explanation? Can you figure out why it detects that in the output for
your test?
Yes, because I have full listings enabled in order to debug the
configure and build process. Which means that the compiler lists out
even the lines that are not compiled.
