            Bug ID: 58468
           Summary: Macro gets undefined when source directory is same as
                    macro name.
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: preprocessor
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ateuscher at datacomm dot ch

Content of file src/test.c:

#ifndef SRC
# error SRC not defined!
#endif

When precompiled from base directory:

cpp -P -DSRC src/test.c

src/test.c:3:3: error: #error SRC not defined!
 # error SRC not defined!
   ^

There seems to be conflict problem with the macro SRC and the directory src.

Tested with MinGW under Windows 7.

Older versions doesn't have that problem.

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Hmm, did the driver accidently convert SRC to src when dealing case insensitive
windows.
