No problems with trunk builds as the whole gtkembedding was overhauled and xpcom/glue/nsDebug.cpp was removed anyway.
non-debug builds properly and also gcc-4.1.2. Probably pragma related?

Benjamin, there's still a lot of DEFINES += -DMOZILLA_STRICT_API in embedding subdirs.

When I substitute "DEFINES += -DMOZILLA_STRICT_API" against "MOZILLA_INTERNAL_API = 1"
or comment out:
#ifdef MINIMO
# For minimo, we would really like to treat this as a LIBXUL
# library so that we can get the correct export defines.
LIBXUL_LIBRARY = 1
#endif
in embedding/base/Makefile.in the debug build compiles successfully.
However, neither solution seems to be correct, or?

Comment 2

Another try was to substitute "Defines += -DMOZILLA_STRICT_API" with "DEFINES += -DXPCOM_GLUE". This changes the error message from
libembed_base_s.a(nsEmbedAPI.o): relocation R_X86_64_PC32 against `NSGlue_Warning'
libembed_base_s.a(nsEmbedAPI.o): relocation R_X86_64_PC32
against `NS_ShutdownXPCOM'
Does it need to link against both xpcom and xpcomglue? Either way the other seems to be unreachable with the present code in nsDebug.cpp.
Help of a build expert would be very appreciated

Apparently the 1_8_1 Branch is more or less not further developed. The last comment was more than a year ago, Gentoo uses the former visibility check and that works also with debug. So close this as WONT for the 1_8_1 Branch.
