MSDN:
".obj files produced with /GL and precompiled header files should not be
used to build a .lib file unless the .lib file will be linked on the same
machine that produced the /GL .obj file. Information from the .obj file's
precompiled header file will be needed at link time."
That explains a lot. Noteworthy is mentioning precompiled headers. That
stuff never ever worked in VC... Presumably /GL silently killed the entry
point in the .lib file.
