## Find stupid system include dependencies and account for them.  Squirts

## a sample .h file to stdout containing [too many of] the right things.

## If you hose the output into "stupid.h", you will get MORE information.

## This takes a while to run, because it checks so many things.

##

## IF YOU HAVE a system/arch/compiler/whatever that is NOT one of:

##   msdos-msc6.x  ultrix-vax ultrix-mips  sunos4.1.x-sparc  solaris2.x-sparc

##   aix-rs6k  linux1.[01].x-x86  freebsd-x86  netbsd-x86 hpux

##   [... hopefully this list will grow very large]

## or even if you aren't sure, you would be doing me and the net in general

## a wonderful service by running this and MAILING me the "full" output, e.g.

##

##    chmod +x stupidh

##    ./stupidh > stupid.h

##    mail hobbit@avian.org < stupid.h

##

## WARNING: You may have to change "cc" to "gcc" below if you don't have

## "cc" [e.g. solaris, thank you very fucking much, Sun].

## Please note any errors this generates, too...

##

## *Hobbit*, 941122 and previous.  VERSION: 1.3 951107

##

## edits: Use a consistent naming scheme, for easier identification and cleanup.

## accomodate gcc's BOGUS assumptions based on input filename.

## added a few more include-names and try-predefines; some swiped from autoconf.

## added a couple of things commonly done as #defines so we can SEE 'em

## Here is where to change "cc" to "gcc" if needed:

### To make a DOS batchfile instead, do this [on a unix box!], xfer results,

### and have "xxx.bat" that types out all the cruft for %INCLUDE%\%1.

### WARNING: I might not have gotten the superquoting exactly right here...

# echo "if exist %INCLUDE%\\${xx}.h call xxx ${xx}"

# echo "if exist %INCLUDE%\\sys\\${xx}.h call xxx sys/${xx}"

### You also need to save and manually run the CPP input file, below.

### I've done this for msc6 and would appreciate results for other compilers.

### Note: if all the previous output went to "stupid.h", it will be

### reincluded in the second part of this.

sed -e '/^#/d' -e '/^[	 ]*$/d' > st00pid.in << 'EOF'

### More recently, some of this was swiped from the "gcc" doc.  Autoconf is

### worth a harder look for more ideas; havent gotten around to it yet.
