X-Git-Url: https://gitweb.git.savannah.gnu.org/gitweb/?a=commitdiff_plain;h=335ef1d189415202ca4f88e5ff5bd1e7928864cb;p=gnulib.git

Avoid Autoconf "was expanded before it was required" warning.

* m4/exponentf.m4 (gl_FLOAT_EXPONENT_LOCATION): Define through
AC_DEFUN_ONCE.
* m4/exponentd.m4 (gl_DOUBLE_EXPONENT_LOCATION): Likewise.
* m4/exponentl.m4 (gl_LONG_DOUBLE_EXPONENT_LOCATION): Likewise.
