When I try to use AC_LANG_PROGRAM in conjunction with AC_EGREP_CPP, I'm
seeing this error:
configure.ac:97: error: possibly undefined macro: AC_LANG_PROGRAM
If this token and others are legitimate, please use
m4_pattern_allow.
See the Autoconf documentation.
My invocation of AC_EGREP_CPP looks like this:
AC_EGREP_CPP([HAVE_GL_GLU_H], [AC_LANG_PROGRAM([[foo]], [[bar]])],
[OPENVRML_HAVE_GL_GLU_H=1],
[OPENVRML_HAVE_GL_GLU_H=0])
If I have an instance of AC_LANG_PROGRAM usage earlier in the file that
has been working fine. However, the error message will point to it.
Only if I remove the first occurrence does the error message point at
the second invocation (the one mentioned listed above).
I am using Autoconf 2.63. (Specifically, the one in Fedora 10.)
