Thanks! I already had dmd installed from a brief look at D

ctRegex is a crock; use regex() instead and it might actually work
better.

Relatedly, how can I add custom compiler flags to rdmd, in a D

For example, -L-lpcre
Configuration variable "DFLAGS". On Windows you can specify it in
the sc.ini file. On Linux: https://dlang.org/dmd-linux.html

The following code, that just runs a regex against a large exim
log
to report on top senders, is 140 times slower than similar C code
using
PCRE, when compiled with just -O. With a bunch of other flags I
got it
down to only 13x slower than C code that's using libc
regcomp/regexec.
