I don't use Windows, so I don't know the details about it, but I can't
understand what you mean for non-Windows either.

The point is, if a library have a:

pragma (lib, "curl");

And I want to use libcurl-gnutls instead, I can't without modifying the source.
Even more, if I don't even have the non-gnutls curl installed, I can't even
compile.

For example:

p.d
---
import l;
void main() {}
---

l.d
---
pragma (lib, "curl");
---

$ dmd -v /tmp/p.d /tmp/l.d -of/tmp/p | grep curl
library   curl
gcc /tmp/p.o -o /tmp/p -m32 -Xlinker -L../lib -lcurl -lphobos -lpthread -lm 
/usr/bin/ld: skipping incompatible
/usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../libcurl.so when searching for
-lcurl
/usr/bin/ld: skipping incompatible
/usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../libcurl.a when searching for
-lcurl
/usr/bin/ld: skipping incompatible //usr/lib/libcurl.so when searching for
-lcurl
/usr/bin/ld: skipping incompatible //usr/lib/libcurl.a when searching for
-lcurl
/usr/bin/ld: cannot find -lcurl
collect2: ld returned 1 exit status

DMD adds the -lcurl and AFAIK, I can't change that without modifying the source
of l.d (which might not be under my control, it could be a system-wide header
for which I have no write-access, of course I could copy and modify it but I
hope we agree that is less than ideal).

Is there any way to avoid that problem right now?
