situations) before going on to tests that run executables with the compiler. Print a friendly error message if it fails. Hopefully, this will help people with borked compilers. This commit was SVN r8898.

# Try to compile and run a simple "exit(0)" application in

# 'language'. A warning is always printed if the application
|
|
# fails to run. Action-if-found is evaluated if the application
|
|
# runs successfully (or compiles if cross-compiling), and
|
|
# action-if-not-found is evaluated if the application fails to
|
|
# run.
|
|
#
|
|
# language-exit should be how to exit cleanly in 'language'.
|
|
# You probably want exit(0) for C/C++ and empty for Fortran.
