can't convert char* to const char* !?

GLcharARB* pC;
glShaderSourceARB(m_Shaders[index][2], 1, &pC, NULL);

error C2664: 'void (GLhandleARB,GLsizei,const GLcharARB ** ,const
GLint *)' :
cannot convert parameter 3 from 'GLcharARB **__w64 '
to 'const GLcharARB ** '
Conversion loses qualifiers

This works:
const GLcharARB** ppA;
memcpy(&ppA, &pVert, sizeof(char*));
glShaderSourceARB(m_Shaders[index][1], 1, ppA, NULL);

What have I done?

Using VC7.1 here.

("%silto%c%cf%cgl%ssic%ccom%c", "ma", 58, 'g', 64, "ba", 46, 10);}
