I have never seen anything like that. Usually the minimal time
to run a D program is something like:
j@debian:~$ time ./hello
Hello world!
real 0m0.001s
user 0m0.000s
sys 0m0.000s
What really amazes me is the difference between g++, DMD and
GDC in size of the executable binary. 100 orders of magnitude!
With GDC those flags(for gdmd):
-fdata-sections -ffunction-sections -L--gc-sections -L-l
help a lot if you want to reduce a size of executable. Besides,
this overhead is the standard library and runtime and won't be
much larger in larger programs.
The last flag should be -L-s
