Subject: Add replacement headers for libbacktrace
X-Git-Url: https://git.cworth.org/git?a=commitdiff_plain;h=937b6ac4bbe9e82838c8be9750bd019d97ad8359;p=apitrace

Add replacement headers for libbacktrace

libbacktrace #include's two header files from GCC.  Provide minimal
replacements for those files.  For filenames.h, declare missing macros
assuming POSIX-style paths.  For dwarf2.h, #include system dwarf.h and
declare missing enum tags and define missing enum values as macros.
