# Taken from mpfr-4.0.1, then modified for LDADD_FOR_TESTS_KLUDGE
dnl Under Linux, make sure that the old dtags are used if LD_LIBRARY_PATH
dnl is defined. The issue is that with the new dtags, LD_LIBRARY_PATH has
dnl the precedence over the run path, so that if a compatible MPFR library
dnl is installed in some directory from $LD_LIBRARY_PATH, then the tested
dnl MPFR library will be this library instead of the MPFR library from the
dnl build tree. Other OS with the same issue might be added later.

from a perfect solution and hides problems with an improper
initialization but at least in single-threaded mode it should work
reliable.
The reason we need this is that a lot of applications don't use
Libgcrypt properly by not running any initialization code at all.
They just call a Libgcrypt function and that is all what they want.
Now with the FIPS mode, that has the side effect of entering FIPS
mode (for security reasons, FIPS mode is the default if no
initialization has been done) and bailing out immediately because
the FSM is in the wrong state. If we always run the init code,
Libgcrypt can test for FIPS mode and at least if not in FIPS mode,
it will behave as before. Note that this on-the-fly initialization
is only done for the cryptographic functions subject to FIPS mode
and thus not all API calls will do such an initialization. */
