# Before this patch:
#
# $ strace php -r 'echo 1;' 2>&1 | grep php.ini
# open("/www/php/lib/php.ini", O_RDONLY)  = 3
# lstat64("/www/php/lib/php.ini", {st_mode=S_IFREG|0640, st_size=46264, ...}) = 0
#
# With this patch:
#
# $ strace php -r 'echo 1;' 2>&1 | grep php.ini
# open("./php.ini", O_RDONLY)             = -1 ENOENT (No such file or directory)
# open("/usr/src/php5_1_full/sapi/cli/php.ini", O_RDONLY) = -1 ENOENT (No such file or directory)
# open("/www/php/lib/php.ini", O_RDONLY)  = 3
# lstat64("/www/php/lib/php.ini", {st_mode=S_IFREG|0640, st_size=46264, ...}) = 0
