           Summary: cygwin/gdc compilation error for legal code (variadic
                    templates)
           Product: DGCC aka GDC
           Version: 0.23
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: major
          Priority: P2
         Component: glue layer
        AssignedTo: dvdfrdmn at users.sf.net
        ReportedBy: tortoise_74 at yahoo.co.uk


The following code fails to compile under gdc on cygwin:
---
import std.stdio;

void myWritefln(T...)(T args)
{
     foreach(arg; args)
         writef("%s", arg);

     writefln();
}

void main() {
        myWritefln("Hi! ", 5, " that's all.");
}
---
F:\projects\Agenda>gdc --version
gdc (GCC) 3.4.4 (cygming special, gdc 0.23, using dmd 1.007))

F:\projects\Agenda>gdc test2.d
cc1d: warning: command line option "-iprefix" is valid for C/C++/ObjC/ObjC++
but
 not for D
test2.d:3: found '...' when expecting ')'
test2.d:3: semicolon expected following function declaration
test2.d:3: Declaration expected, not ')'
test2.d:5: no identifier for declarator args
test2.d:5: semicolon expected, not ')'
test2.d:5: Declaration expected, not ')'
test2.d:8: no identifier for declarator writefln
test2.d:9: unrecognized declaration

It works fine with dmd.

I am also informed it works with the following:
gdc (GCC) 4.1.1 20060524 (  (gdc 0.23, using 
dmd 1.007))" (Linux x64 version):
