           Summary: Long environment variable value causes link failure.
           Product: D
           Version: 1.015
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: tortoise_74 yahoo.co.uk


Hi
  I had some problems getting DMD to play nicely with cygwin. It turns out the
problem was down to a long environment variable value. As a newcomer to D I was
very confused. It was not at all obvious what was happening.

Regards,

Bruce.

I can confirm this also happens on the latest version (v2.002)

Ouch.  That must have taken ages to figure out.  

Actually it seems to be related to both the variable name and its value. For
instance "XCCINCDIR" worked ok, and many values of GCCINCDIR are ok for me. 
But other variables caused the problem too, like "FOOINCDIR".  I can't really
determine a pattern.

In any event you should probably use 'dmd' to compile D code and not 'dmc'
(which is a C++ compiler) ;-)

Keep the version at the oldest, not the newest, relevant value, please.
