* system/gc: don't export markStackAndRegisters * compiler/cgen: unexport internal symbols As these functions are Nim-specific walkaround against C's optimization schemes, they don't serve any purpose being exported. * compiler/cgen: don't export global var unless marked * compiler/ccgthreadvars: don't export threadvar unless marked * tests/dll/visibility: also check for exports This ensure that these changes don't break manual exports. * compiler/cgen: hide all variables created for constants * compiler/ccgtypes: don't export RTTI variables * compiler/ccgexprs: make all complex const static * nimbase.h: fix export for windows * compiler/cgen, ccgthreadvars: export variables correctly For C/C++ variables, `extern` means that the variable is defined in an another unit. Added a new N_LIB_EXPORT_VAR to correctly export variables.
