The test should check for _glp_lpx_simplex symbol (note the leading 
underscore).
But maybe the safest solution is to write a custom test that uses 
lpx_simplex instead.
Indeed, the user API hasn't changed, but this API is #define'd in GLPK 
headers, and
the symbol to which it's #define'd has changed. For instance:

#define lpx_simplex glp_lpx_simplex

became

#define lpx_simplex _glp_lpx_simplex

So, if you write a custom test that tries to link a piece of code using 
lpx_simplex,
this should be portable. OTOH, you must check for the header first, because
you'll need to include it in your custom test.
