GHC Task Ticket # 601 suggests replacing GMP with OpenSSL's Bignum

From the ticket, this looks very scary:

example).
Does this mean I can't distribute my Haskell app as a commercial
application? I certainly don't want to distribute source code and
I've got no idea how to compile a Haskell app other than using ghc
--make, which creates a single exe ie with static linkage.
GHC only statically links Haskell code. It dynamically links to GMP
and the system C library and other C libs.
So you're fine.
On unix you can check for yourself with ldd. It lists all the shared
libs that your program needs. For example:
$ ldd /usr/lib/ghc-6.4.2/ghc-6.4.2
libreadline.so.5 => /lib/libreadline.so.5 (0x00002b568fca6000)
libncurses.so.5 => /lib/libncurses.so.5 (0x00002b568fde3000)
libdl.so.2 => /lib/libdl.so.2 (0x00002b568ff3f000)
libm.so.6 => /lib/libm.so.6 (0x00002b5690042000)
libgmp.so.3 => /usr/lib/libgmp.so.3 (0x00002b569019a000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00002b56902cf000)
libc.so.6 => /lib/libc.so.6 (0x00002b56903e4000)
/lib64/ld-linux-x86-64.so.2 (0x00002b568fb8e000)
Is this also true on Windows?
I've got a feeling that it's not because my program (ie main.exe + my own
C++ DLL) runs on a plain WindowsXP installation that doesn't have anything
else installed on it (apart from the Microsoft C runtime that comes as
standard and which presumably doesn't contain GMP).
Thanks, Brian.
