Issue ID: 16289
Summary: no extern(C++) mangling for unsigned long
Product: D
Version: D2
Hardware: x86_64
OS: Linux
Status: NEW
Severity: enhancement
Priority: P1
Component: dmd

The C++ mangler conflates mangling for unsigned, unsigned long, and unsigned
long long depending on the target architecture. Those are separate manglings in
C++, independent of their target size.
This leads to several linking problems w/ C++ code, in particular when a size_t
parameter is involved.
We already have some places in cppmangle where we properly handle
Id.__c_long/Id.__c_ulong. This should be extended to size_t parameters in
extern(C++) functions. We might also consider to change the size_t declaration
to exactly match the C++ definition of the used platform.
