Yes this is the place for bug reports.

I need more information to properly fix it.  I can make some 
assumptions, but I would rather ask you to say it directly.

1.  You sent a patch.  What are the symptoms?  I am guessing: In 
l_ftos.cc, "isnan" and/or "isinf" undefined on compile.  In the test 
script, it doesn't accept "==".

2. What version of gnucap?  I am guessing: it must be 0.34, because that 
is the only one with the "usage" check in the test script, but I 
thought the "isnan" was fixed.

3. What computer, OS, etc..?  I am guessing: based on other 
communication with you, a BSD system, but not FreeBSD.  Is it NetBSD or 
OpenBSD???

4. What compiler?


I will change the test script.  Linux uses "bash" when you ask for "sh".  
I verified that "dash" doesn't work, and that your patch fixes it.  I 
believe that the Linux "dash" is the standard BSD shell.  I also 
verified the problem and your fix on a Sun.  Thank you.

On <math.h> .....  This is not a standard C++ header.  It's a standard C 
header.  The preferred C++ header is <cmath>.  Can you check this for 
me?  If it is "isnan" and "isinf", why does the configure script not 
catch it?  <cmath> is not included explicitly because it is included by 
<complex> on my system.  If <math.h> fixes it, why do the trig 
functions work?   I need more info on this one.
