pkgsrc/lang/php5 tests failures

[Chris Ross <cross+netbsd%distal.com@localhost>]

  So, I was just rebuilding packages on my production NetBSD sparc64  
machine, currently running 5.1_RC1.  Upon deciding to upgrade my PHP  
installation to 5.3 (php-5.3.2nb2), I did a full build, then ran make  
test.  After more than an hour, I was presented with many failed  
tests.  Interestingly, going into lang/php5 (php-5.2.13nb1) and doing  
the same produced even more failed tests.  So, I'm guessing it's not  
dire, but was wondering if anyone knows if these are poor tests, or if  
there's some issues with the PHP compilation on NetBSD, or 64-bit  
NetBSD, or BE 64-bit, etc.

  Of interesting note were some 64-bit failures, occurring in both  
php revisions:

Test & operator : 64bit long tests [tests/lang/operators/ 
bitwiseAnd_basiclong_64bit.phpt]
Test ~N operator : 64bit long tests [tests/lang/operators/ 
bitwiseNot_basiclong_64bit.phpt]

Test >> operator : 64bit long tests [tests/lang/operators/

log10_basiclong_64bit.phpt]
Test var_dump() function [ext/standard/tests/general_functions/ 
var_dump_64bit.phpt]

  ...and, some "basic functionality" tests on what seem like very  
simple operations/syscalls:

chmod() basic fuctionality [ext/standard/tests/file/chmod_basic.phpt]
proc_nice() basic behaviour [ext/standard/tests/general_functions/ 
proc_nice_basic.phpt]
proc_open [ext/standard/tests/general_functions/proc_open02.phpt]
Test usleep() function [ext/standard/tests/general_functions/ 
usleep_basic.phpt]
Test log() - basic function test log() [ext/standard/tests/math/ 
log_basic.phpt]

  Can anyone tell me if these are known issues?  And, should I expect  
any software I run under PHP to fail in areas such as these, or are  
the tests written presuming things that are unrealistic or inaccurate?

  Thanks....
