- appears it's not safe change
- it's not NOOP on x64_64

bulding with -D_FILE_OFFSET_BITS=64 [1] made pear fail on all three 
arches (x86_64, i686, i486)

did not get any clear indication why it failed, just exited with 255 
error, nothing useful when stracing.
to debug, run "builder -bp php-pear-Archive_Tar" (or any other pear 
package that uses pear to unpack)

i've built two versions of php on same machine, with [2] and without [3] 
the define. both directories contain poldek indexes and build.log

[1] 
http://git.pld-linux.org/?p=packages/php.git;a=commitdiff;h=a0106ed918ffc6ff961caa33a8e27003bcfc3133
[2] http://carme.pld-linux.org/~glen/th/x86_64/_FILE_OFFSET_BITS/on/
[3] http://carme.pld-linux.org/~glen/th/x86_64/_FILE_OFFSET_BITS/off/

you need php53-{program,xml,pcre,zlib} packages for pear to work

perhaps the problem is that it the flag not be used alone? perhaps zlib 
or libxml should be built with same cflags? i don't know.
