***********************************************
Some symbols are missing, which raises linking errors when I use gdc (under Mac
OS X) - linking.txt.

See the output of nm libgphobos2.a attached (as the rightmost
missing_symbols.txt.. apparently can't delete/rename attachments.

Since then I've recompiled with gcc-4.5.3, but am facing the same issues. I'm
also attaching exactly the symbols reported as missing by ld (as the leftmost
missing_symbols.txt).

# examples for one of the missing symbols

# version just installed, compiled for x86-64
$ nm /opt/usr/local/lib/libgphobos2.a 2>&1 | grep _D11TypeInfo_AC6__initZ
0000000000001f20 S __D11TypeInfo_AC6__initZ
                 U _D11TypeInfo_AC6__initZ
                 U _D11TypeInfo_AC6__initZ
                 U _D11TypeInfo_AC6__initZ
# ---   unresolved symbols start with only ONE underscore .. (like on 32-bit
dmd?)

# GdcMac based on GCC 4.2.1 and dmd 1.064, 64-bit (for reference)
$ lipo -extract x86_64 /usr/lib/libgphobos.a -output libgphobos-x86_64.a
$ nm libgphobos-x86_64.a 2>&1 | grep _D11TypeInfo_AC6__initZ
                 U __D11TypeInfo_AC6__initZ
                 U __D11TypeInfo_AC6__initZ
00000000000003c0 S __D11TypeInfo_AC6__initZ
# ---   notice that all of the symbols start with TWO underscores

# DMD 2.052, official binary, only 32-bit
