--------------------------------+-------------------------------------------
 Using MacPorts 2.0.3 on OS X Lion 10.7.1 and Xcode 4.2 (Developer
 Preview), building gettext-0.18.1.1 using Portfile r81158.

 If your xgettext does this:

 {{{
 $ xgettext
 xgettext: A --flag argument doesn't have the
 <keyword>:<argnum>:[pass-]<flag> syntax: gettext:1:pass-c-format
 }}}

 which I noticed when trying to install gnome-doc-utils which failed
 because of this, then you may be seeing a bug in clang.

 Specifically:

 {{{
 $ clang --version
 Apple clang version 3.0 (tags/Apple/clang-209.9.2) (based on LLVM 3.0svn)
 Target: x86_64-apple-darwin11.1.0
 Thread model: posix
 }}}

 The clang bug is documented here:

 http://lists.cs.uiuc.edu/pipermail/llvmbugs/2011-May/018101.html

 I confirmed that this is what's biting me in the ass by building gettext
 using the same configure args that MacPorts does, but setting CC=gcc and
 CXX=g++, removing clang from the picture.  It now builds an xgettext
 binary that does this, as expected:

 {{{
 $ xgettext
 xgettext: no input file given
 Try `xgettext --help' for more information.
 }}}

 Simple patch to do the override attached, but the bigger question is: why
 is MacPorts using clang?!  What was wrong with gcc -O2 ... :-(
