          Issue ID: 24294
           Summary: ImportC: required GCC version?
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: kdevel at vogtner.de

With GCC 4.3.2 installed using the ImportC feature (example in issue #24293)
fails:

$ dmd xmysqltest1.d 
cc1: error: unrecognized command line option "-Wno-builtin-macro-redefined"
xmysqltest1.d(2): Error: C preprocess command cpp failed for file cmysql.c,
exit status 1

GCC 4.6.4 and higher support the requested switch.
