A number of people have tried to fix configuration problems by editing

acconfig.h. (Despite comments at the top of the file.) I think they're
|
||||
confused because anything.h looks like a regular source file name.

Maybe acconfig.h could be called acconfig.extra or something?

Using the macro AC_CHECK_LIB, if the library name contains a dot (which is

the case of the library complib.sgimath on Irix 5.x) a syntax error occurs
|

because the corresponding cache variable name contains a dot.

Should dots be converted to underlines in variable names by autoconf?
