# If the C compiler in not in ANSI C mode by default, try to add an option

# options that select ANSI C on some system or another. It considers the
50
# compiler to be in ANSI C mode if it defines @code{__STDC__} to 1 and
51
# handles function prototypes correctly.

# Patched by monty to only check if __STDC__ is defined. With the original
54
# check it's impossible to get things to work with the Sunpro compiler from

58
# compiler has been set to accept ANSI C; if not, the shell variable
59
# @code{am_cv_prog_cc_stdc} is set to @samp{no}. If you wrote your source
60
# code in ANSI C, you can make an un-ANSIfied copy of it by using the
61
# program @code{ansi2knr}, which comes with Ghostscript.
