Hi again Richy, Just wanted to ask if anyone's succeeded in building CLN on MinGW / MSYS ? Is this something that other people have shown an interest in? I get the following error when I try to ./configure && make:

g++ -g -O2 -I../include -I../include -I./base -Ibase -c ./base/random/cl_random_from.cc -DDLL_EXPORT -DPIC -o .libs/cl_random_from.o ./base/random/cl_random_from.cc: *In constructor `cln::random_state::random_state()':* ./base/random/cl_random_from.cc:68: *error: `::get_seed' has not been declared* make[3]: *** [cl_random_from.lo] Error 1

The problem could be as simple as needing to alter the #if stuff like (defined(_WIN32) && defined(__GNUC__)) -- I think that MinGW may use slightly different macros eg WIN32 in place of _WIN32. Or it could be more complex, I know that MinGW doesn't implement glibc so you might need more complicated #ifdefs and provide some aliases to MFC library calls. My experience with MinGW is that it runs a lot more quickly -- both compiling and then running the compiled code. The Cywin POSIX layer seems to slow things down quite a bit in computationally intensive stuff.
