MinGW64 build issue

[rickyboy]

Lutz,



The MinGW (32-bit) compile of newLISP is clean as a whistle.

But when I use any of the MinGW 64-bit toolchains, the compiler complains about initializers not being constant in nl-import.  (The other *.c files compile just fine, albeit with more warnings.)



BTW, /MinGW now points to a 64-bit MinGW toolchain, and I added some -Wno-* flags to suppress some warning noise.

Curious as to why the 32-bit gcc did not complain about this too.  http://stackoverflow.com/questions/3025050/error-initializer-element-is-not-constant-when-trying-to-initialize-variable-w">Some dudes on SOF claim that the C standard says that you can't do this.  (Even though, I think it's cool that you can.)  BTW, 64-bit gcc on Linux has no problem with this.  So, I wonder if there is a GNU extension that enables the 32-bit MinGW to accept this, but which is turned off by default in the 64-bit MinGW toolchain.



Have you tried using the 64-bit target compilers of MinGW to compile newLISP before?  Curious.



Thanks for any feedback.
