In new 1.4.0 release, **nimbase.h** defies the macro `NIM_STATIC_ASSERT`, trying some possible implementations depending on C compiler version used. The last fallback option uses a `NIM_STATIC_ASSERT_AUX` trick ( **nimbase.h** line **275** ), which does not work. This macro is used twice in the following source (lines **323** and **542** ), both lines typedef the same symbol `NIM_STATIC_ASSERT_AUX`, gcc blames on redefenition. We need some better fallback static assert (there are many possible solutions floating around, one is mentioned in the code).
For me, the strong point of Nim is, it is still usable for ancient systems (and some people are bound to support them). Let us keep it, well, if not forever, but a little more at least? (works for me after a dirty but trivial fix with my current gcc). Sorry for a poor wording, I registered just to report this.
