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

# to output variable @code{CC} to make it so.  This macro tries various

# options that select ANSI C on some system or another.  It considers the

# compiler to be in ANSI C mode if it defines @code{__STDC__} to 1 and

# handles function prototypes correctly.

#

# Patched by monty to only check if __STDC__ is defined. With the original 

# check it's impossible to get things to work with the Sunpro compiler from

# Workshop 4.2

#

# If you use this macro, you should check after calling it whether the C

# compiler has been set to accept ANSI C; if not, the shell variable

# @code{am_cv_prog_cc_stdc} is set to @samp{no}.  If you wrote your source

# code in ANSI C, you can make an un-ANSIfied copy of it by using the

# program @code{ansi2knr}, which comes with Ghostscript.
