#40186: guide needs to be updated to reflect current compiler behavior
---------------------+---------------------
 Reporter:  egall@…  |      Owner:  markd@…
     Type:  defect   |     Status:  new
 Priority:  Normal   |  Milestone:
Component:  guide    |    Version:  2.2.0
 Keywords:           |       Port:
---------------------+---------------------
 The guide currently says this about `configure.compiler`:
 {{{
 configure.compiler
 Select a compiler suite to fill the compiler environment variables. All
 variables/tools a compiler suite can provide are set. Manually set
 variables are not overwritten. Dependencies are not added for you, as they
 may be just build- or also run-dependencies. Keep in mind that not all
 compiler suites might be available on your platform: gcc-3.3 is available
 on Mac OS X 10.3 and 10.4 PowerPC, gcc-4.0 is available on 10.4+, gcc-4.2
 and llvm-gcc-4.2 are available on 10.5 and 10.6, and clang is available on
 10.6.

 Only use it if a port really needs a different compiler.
 }}}
 This is wrong as of MacPorts 2.2.0.
