           Summary: DMD 1.018: Fix for bug657 breaks other code
           Product: D
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: P1
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: aldacron@gmail.com


The following worked for over three years until DMD 1.018:

####################
version(Windows)
    extern(Windows):
else
    extern(C):

typedef void function() foo;
...
#####################

Compilation with DMD 1.018 results in the following error:

"Declaration expected, not 'else'"

Adding brackets compiles successfully:

####################
version(Windows)
{
    extern(Windows):
}
else
{
    extern(C):
}

typedef void function() foo;
...
#####################

Unfortunately, this form causes the executable to crash on both Windows and Linux. It appears the extern statements are being ignored.

This affects several packages in Derelict, causing them to be unusable with 1.018 without a rather large rewrite. I assume this is a result of the fix for bug657.

This bug is blocking the Arc v.2 release.

According to the changelog for DMD 0.74:
* Version declarations can now wrap attribute : and they'll stick.

Why did this feature suddenly turn into a bug?

The functionality was restored by introducing extern(System) for exactly this situation. I'll mark this as fixed.
