Issue ID: 21944
Summary: importC: Support parsing # line marker directive
extensions
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: major
Priority: P1
Component: dmd
Assignee: nobody at puremagic.com
Reporter: ibuclaw at gdcproject.org
The gcc preprocessor (gcc -E) spits out code like this:
---
# 1 "test.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 31 "<command-line>"
# 1 "/usr/include/stdc-predef.h" 1 3 4
# 32 "<command-line>" 2
# 1 "test.c"
---
The CParser seems to successfully ignore these directives, though it does so
using the `panic()` function.
However if a line marker appears in the middle of a declaration, e.g:
---
struct Foo {
int var;
#1 "foo.c" 3 4
};
---
An error occurs.
