[Bug-gnulib] proposed patch to mathl module to assume C89 or better

[Paul Eggert]

gnulib is now assuming C89 or better.  I looked through gnulib for K&R
code and found the following relics in the mathl module.  OK to
install the following patch?

2003-09-08  Paul Eggert  <address@hidden>

        * acosl.c (main): Use a prototype.
        * asinl.c, cosl.c, expl.c, frexpl.c, ldexpl.c, sinl.c,
        tanl.c: Likewise.
