this is hard to guess. configure creates a small file in the current
language (default is C), containing "#include <gmpxx.h>" and tries to
process it. The "usability" check tries to compile it, which
"presence" means processing by the preprocessor only; but in any
case, it's not a mere check whether the file exists.
These attempts are logged in config.log; visit the log to see the
exact test source file and the error messages from the compiler and
preprocessor.
HTH,
Stepan
