            Bug ID: 82510
           Summary: C compiler ignores user definition of log
           Product: gcc
           Version: 4.8.5
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: doug at idaccr dot org
  Target Milestone: ---

Created attachment 42338
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=42338&action=edit
compile with "gcc -O0 log-bug.c" - it should print 2.5 when run.

When I define my own "log" function in a C program the one defined in math.h
is used, even when I don't include math.h.
