[Mesa-dev] Makedepend running forever on Fedora 16

[Thomas Hellstrom]

Hi, all

The commit

commit 63e7a4c6e5bf51d8090046ebc5adcb4207448565
Author: José Fonseca <jfonseca at vmware.com>
Date:   Wed Nov 9 10:20:51 2011 +0000

     mesa,glsl,mapi: Put extern "C" { ... } where appropriate.

     Probably a several places missing, but enough to cover all headers
     (in)directly included by uniform_query.cpp, and fix the MSVC build.


makes "makedepend" run forever in the src/mesa subdirectory on Fedora 
16, x86,
I haven't seen this happening on other distros.

Any fedora- or Makedepend insights would be appreciated.

Preliminary investigations show that makedepend appears to get stuck 
parsing the line

#if FEATURE_dlist,

consuming 95% CPU. No IO or memory usage growth.  A typical ctrl-c 
backtrace when this happens is
