             Bug #: 13237
           Summary: scan-build doesn't understand -isystemDIR
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com
        ReportedBy: bbannier+llvm_bugs at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


clang mirrors gcc in that it allows an optional space when specifying include
paths, i.e. it supports both `-I/DIR and `-I /DIR` or along the same line
`-isystem/DIR` and `-isystem /DIR`.

scan-build understands most of these as well, but not the `-isystem/DIR` form
without the extra space.

This seems inconsistent and is cumbersome to deal with. Is there an option to
allow scan-build to use that form as well?
