On Linux using 2.7.1 release if i have a file called 'escape"me' and preprocess the file it generates the following #line directive

#line 1 "/home/tom/Desktop/mcpp-2.7.1/src/escape"me"

with gcc it generates

# 1 "escape\"me"

which has the double quote in the middle escaped.

is this intended or is it a bug?

  MCPP simply does not support such a quirk of filename. Does it have any meaning in real world programs?
  
  Though GCC emits the line at 'escape"me':
  
  # 1 "escape\"me"
  
  , it emits an error on the source "inc_esc.c":
  
  #include "escape\"me"
  
  as:
  
  inc_esc.c:1:19: warning: extra tokens at end of #include directive
  inc_esc.c:1:22: error: escape\: No such file or directory
  
  Anyway, I don't think it has any meaning for a preprocessor to support such an obfuscated code.

  Although i see no real reason to use a file name with such a character it is an allowed file name by the Linux operating system and therefore should be allowed in a tool chain in my opinion.
