Error when cross compiling using zig cc

[alliby]

i tried to cross compile nelua code from my linux machine to windows using zig cc and mingw
using both these commands

nelua test.nelua --cc="zig cc -target x86-windows"
nelua test.nelua --cc="x86_64-w64-mingw32-gcc"

for this code:

## pragma{nogc=true}
##[[
-- Compile GLAD
--------------------------------------------------
cinclude "glad/glad.h"
cfile "glad/src/glad.c"
cincdir "glad/include"

-- generate bindings for glad
local nldecl = require 'nelua.plugins.nldecl'
if not fs.isfile('glad/init.nelua') then
   nldecl.generate_bindings_file{
      include_dirs = { 'glad/include' },
      output_file = 'glad/init.nelua',
      parse_includes = {'glad/glad.h'},
   }
end
--------------------------------------------------
]]

-- Include GLAD
require "glad"

give the same error for the generated glad bindings:

test.nelua:1:1: from: AST node Block
## pragma{nogc=true}
^~~~~~~~~~~~~~~~~~~~
init.nelua:1:1: from: AST node Block
global gladGLversionStruct: type <cimport,nodecl,ctypedef'gladGLversionStruct'> = @record{
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
init.nelua:7541:8: error: in variable 'INT_FAST16_MAX' declaration: constant value `9223372036854775807` for type `clong` is out of range, the minimum is `-2147483648` and maximum is `2147483647`
global INT_FAST16_MAX: clong <comptime> = 9223372036854775807
       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

a workaround for this is manually compiling the generated c code from nelua using the appropriate c compiler

Your pragma syntax is wrong; here's the correct one: ## pragmas.nogc = true

Actually, I have navigated in Nelua's internals some external libraries and have found this syntax. I have never seen this kind of syntax before.
