Bug#456628: compiz: fails to start when POSIXLY_CORRECT is set

["brian m. carlson" <sandals@crustytoothpaste.ath.cx>]

Package: compiz
Version: 0.6.3~git20071208.25941d14-1
Severity: important
Tags: patch

When POSIXLY_CORRECT is set, compiz fails to start:

lakeview ok % Checking for Xgl: not present. 
Detected PCI ID for VGA: 00:02.0 0300: 8086:27a2 (rev 03) (prog-if 00 [VGA])
Checking for texture_from_pixmap: grep: -c: No such file or directory
/usr/bin/compiz: line 153: [: -gt: unary operator expected
not present. 
Trying again with indirect rendering:
Checking for texture_from_pixmap: grep: -c: No such file or directory
/usr/bin/compiz: line 153: [: -gt: unary operator expected
not present. 
aborting and using fallback: /usr/bin/metacity 
metacity: Unknown option --fast-filter

This is because under POSIX, the first non-option argument terminates
option processing, and so the grep invocation produces no valid output
(since -c comes at the end).  A patch is attached to reorder the
arguments to grep so that it works even in this case.
