Allready a few newer revisions up but still working on a few things so next version should be interresting.
One of the nasty things with some of the mingw packages are that they need to have there paths mangled from unix to windows absolute paths to work correctly.
As you can guess this makes the compiler unrelocatable, so after a lot of work i created post install scripts to run the nessesary sed commands on the parts that need it like cmake.
The downside is that the place you install this in is where you need to keep it, but then again msvc is not really relocatable either

.
New additions:
mcpp: a C/C++ preprocessor you can use as a replacement for gcc's cpp. It has strict support for C98 and older so dont use with sources that rely on newer runtimes.
nspr: mozilla's socket library.
docbook: sgml from cygwin.
fixed a bug in mingw64's binutils.
Bullet: physics library.
stxxl: standard library for huge data loads.
xerces: xml library and tools.
mpatrol: memory debugging tools.
putty: free telnet/shh client. (outlawed in some countries because of encrytion, freedom of speech seems to have a hard time in some places heh).
perl: a version of perl built for MinGW64. (Also needs to have its paths mangled so expect first start to take a bit while sed runs on the scripts).
Productivity is a state of mind.
