Patch for autoconfig-2.13: AC_TRY_COMPILE plus F77.

[Wolfgang Glas]

I'm using autoconfig-2.13 at an IRIX6.5 workstation using gcc-2.95.2.
I recognized, that AC_TRY_COMPILE doesn't run with f77 programs, because the
conftest.f program, which is implicitly created by the shell script with

cat > conftest.f << EOF
      program main
....
      endEOF

contains mor than the above snipped lines, because my shell does not stop at
EOF.
The following small patch solves my problem by introducing an additional newline
in
acgeneral.m4:

I'd appreciate, if you checked in my patch for availability in later versions of
autoconfig.


Sincerely,
