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 tango.math.Math.min!(dchar,uint).min parameter min._param_zu is already 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.
