Heh, you're right, I misread the Perl script (or rather, didn't
pay
attention to that little flag named $combine). The original

indeed compile everything all at once. I'll have to change my

version to do the same. :)
The perl script achieves that by adding the "-combine" option to
the invocation of gdc (perl/l626). That is a deprecated option.
Newer one is to use "-flto" and, also, if the output is an exe,
"-fwhole-program" could be added, too.
see here:

I think there is no problem to provide "-flto" to gdc even if
there is just only one source file (unlike the "$combine" flag
that is activated only for multiple source files: perl/l490).
More, apparently, since gcc 4.6, that "-combine" flag seems to be
inert:
