Recently I tried compiling goshawk's gdc,1.045 at the moment, for
Windows using TDM's GCC/mingw32 patches and build files.  When I started
I chose Cygwin as an environment because the MinGW website was down at
the time.  The compiler has been successfully built and the process to
build it somewhat documented from scratch.

However, when attempting to compile tango 0.99.8 I ran across a template
error that I need help finding the cause of.

When compiling 'tango/text/Regex.d' GDC outputs the following messages.

tango\math\Math.d:212: Error: function
defined

tango\math\Math.d:2426: Error: template instance
tango.math.Math.min!(dchar,uint) error instantiating

With Linux I can build tango using the same GDC/GCC version compiled
from source.
Also the second message should actually read 'tango\text\Regex.d:2426'
but does not.

I have reduced it down to a specific template signature
void max(T...)(T arg)
{}

As a side note, I am attempting to rebuild using the msys environment to
rule out any cygwin/posix/mingw inconsistencies.  I have built gdc
successively with msys before.

I was hoping to have tango working with gdc before releasing my notes on
building so that I could better test it.  But if someone would like to
try it I can post them.

Could you post the bug report on bitbucket? It will be easier to keep track of that way.
