PAC_PROG_F77_EXCLAIM_COMMENTS

 nl Synopsis: PAC_PROG_F77_EXCLAIM_COMMENTS([action-if-true],[action-if-false])

Notes

Check whether ! may be used to begin comments in Fortran.

This macro requires a version of autoconf after 2.13; the acgeneral.m4 file contains an error in the handling of Fortran programs in AC_TRY_COMPILE (fixed in our local version).
