Well, not a 100% really. How are you parsing/planning to parse this?
---
[Environment]
DFLAGS=-w -g

[Environment-X86]
DFLAGS+=-L-L/usr/lib32

[Environment-X86_64]
DFLAGS+=-L-L/usr/lib64

[Environment-release]
DFLAGS+=-L-lphobos

[Environment-debug]
DFLAGS+=-L-lphobos_d

[Environment-linux]
DFLAGS+=-L-lrt -L-lpthread -L-ldl

[Environment-myversion]
DFLAGS=
---

What do I get if I do:
dmd file.d
dmd -release file.d
dmd -debug file.d
?
I think we either need a new section:
---
[Environment-default]
DFLAGS+=-L-lphobos
---
or something (that can't be used in a -version), or a way to *replace* a flag
(the former seems more reasonable).

Or maybe I'm not getting this right.
