Yeah just use a def file. This is start of def file I used to sort out a
lib for opengl, put the name you want first and what you've got second

=========
; opengl32.dll has __stdcall functions but doesn't follow the std call
; name mangling convention. so we need to sort the mess out.

LIBRARY opengl32
EXETYPE NT
SUBSYSTEM WINDOWS
EXPORTS

_glAccum at 8 = glAccum
=========

Use the def file with implib to create a client .lib.

> implib name.lib name.def
