[Patch] ld: DEFINED builtin is not correctly computed in map file

[Tristan Gingold]

Hi,

this patch fixed a small bug during map file generation.  Because  
lang_statement_iteration was not incremented,
all defined symbols appear to be defined from the beginning.  This is  
not correct according to the
documentation.

Reg-tested on x86-linux, test included.

Tristan.

d/ChangeLog:
2007-08-27  Tristan Gingold  <gingold@adacore.com>

         * ldlang.c (lang_map): Increment lang_statement_iteration so  
that
         DEFINED() expressions are correctly computed.

         * ld-script/map-address.d,
         * ld-script/map-address.t: Add a test for testing DEFINED in  
map
         output.
