autoconf 2.13 bug

[Vadim Zaliva]

Hi!

Autoconf version 2.13 under RedHat Linux version 7. gcc version 2.96.

AC_TRY_RUN macro adds following code at the beginning of
test program:

#ifdef __cplusplus
extern "C" void exit(int);
#endif

This cause following compilation error under gcc 2.96:

/usr/include/stdlib.h:578: declaration of `void exit (int) throw ()'
throws different exceptions
configure:3376: than previous declaration `void exit (int)'
configure: failed program was:

Looks like your declaration of exit() conflicts with one from stdlib,
which under C++ have 'throw' clause.

Sincerely,
Vadim
