configure: error: no acceptable C compiler found in $PATH (+possible solution)

[Kreek, Fred]

Hi,
 
I found a bug in a configure script. A problem is that I do not have easy 
access to the internet, so checking whether the bug still exists in the newest 
version of autoconf is a problem. At the end of this mail there is a transcript 
of the commands I entered.
 
I tried to install PDFlib-Lite-5.0.4p1-Unix-src. The installation includes a 
step where configure should be run. I did so. But to my horror :) the script 
failed giving me a message that I do not have an acceptable C compiler (See 
transcript). Strange enough, since I do have a C compiler, but a colleague of 
me could run configure without any problem.
 
It took some effort but I think I found the problem. While running configure, 
the following code is executed (several times):
<snippet>
# The user is always right.
if test "${PATH_SEPARATOR+set}" != set; then
  echo "#! /bin/sh" >conf$$.sh
  echo  "exit 0"   >>conf$$.sh
  chmod +x conf$$.sh
  if (PATH="/nonexistent;."; conf$$.sh) >/dev/null 2>&1; then
    PATH_SEPARATOR=';'
  else
    PATH_SEPARATOR=:
  fi
  rm -f conf$$.sh
fi
</snippet>
This looks like it should work, but it does not. 
The problem is the fact that I use ksh. With ksh you have 2 variables defining 
the path: $PATH, but also $FPATH. Due some problems in the configuration my 
$FPATH contains the current directory. This results in conf$$.sh being found, 
even when a ':' is the path separator

Possible Solution:
reset $FPATH during this part of the script

Yours,

FK
