           Summary: gdmd should use dmd.conf and $DFLAGS
           Product: DGCC aka GDC
           Version: 0.24
          Platform: All
        OS/Version: Mac OS X
            Status: NEW
          Severity: major
          Priority: P2
         Component: glue layer
        AssignedTo: dvdfrdmn@users.sf.net
        ReportedBy: afb@algonet.se


It would be much easier to do global overrides, such as the ones needed for using Tango (-version=Posix -version=Tango), if the dmd-script wrapper supported the dmd.conf configuration file and the $DFLAGS environment variable... Earlier the compiler .spec was used for this purpose, but that doesn't seem to work anymore.

The DMD documentation says:
----
DFLAGS
    The value of DFLAGS is treated as if it were appended to the command line
to dmd

----
dmd.conf Initialization File

dmd will look for the initialization file dmd.conf in the following sequence of directories:

   1. current working directory
   2. directory specified by the HOME environment variable
   3. directory dmd resides in
   4. /etc/

If found, environment variable settings in the file will override any existing settings. This is handy to make dmd independent of programs with conflicting use of environment variables.

Environment variables follow the [Environment] section heading, in NAME=value pairs. The NAMEs are treated as upper case. Comments are lines that start with ;. For example:

; dmd.conf file for dmd
; Names enclosed by %% are searched for in the existing environment
; and inserted. The special name %@P% is replaced with the path
; to this file.
[Environment]
DFLAGS="-I%@P%/../src/phobos"
