support for non-standard C compilers (without fopen, FILE*, ...)

Hi, recent versions check if $CC supports fopen, FILE* and so on. This breaks environments that don't have / libc.a. Wouldn't the autoconf way to be to /* undef HAVE_STDIO_H */ but leave the source code to handle this instead of aborting? Is it possible to writing something in configure.in to k

how to support compilers that cannot create executables?

Hi, when compiling libraries, it technically is not required to have a compiler to create executables. We might have a lib with unit tests where the unit tests work on linux and windows only, but not on a small embedded platform. On this platform it might be complicated, special and non-standard t

how to retrieve expanded variables from configure?

hi all im not very familiar with autoconf currently so im not sure my following assumptions are correct so, afaik, autoconf and its resulting configure script set many variables e.g. exec_prefix or bindir, ... what i try to achive is extract an expanded representation of all variables configure c
