EasyBMP Cross-Platform Bitmap Library

In the EasyBMP.h header, the following code:
#ifdef _MSC_VER
// MS Visual Studio gives warnings when using
// fopen. But fopen_s is not going to work well
// with most compilers, and fopen_s uses different
// syntax than fopen. (i.e., a macro won't work)
// So, we'lll use this:
#define _CRT_SECURE_NO_DEPRECATE
#endif

should be changed to this:
#ifdef _MSC_VER
// MS Visual Studio gives warnings when using
// fopen. But fopen_s is not going to work well
// with most compilers, and fopen_s uses different
// syntax than fopen. (i.e., a macro won't work)
// So, we'lll use this:
#ifndef _CRT_SECURE_NO_DEPRECATE
#define _CRT_SECURE_NO_DEPRECATE
#define _UNDEF_MSVC_CRT
#endif
#endif

and this should be appenden to the end of the header:
#ifdef _UNDEF_MSVC_CRT
#undef _CRT_SECURE_NO_DEPRECATE
#endif

Additionally, there is this warning for an unused variable:
easybmp.cpp(994) : warning C4101: 'ZeroWORD' : unreferenced local
variable
