Compiling externals: strcasestr etc.

[Thomas Fischer]

Hello,

while compiling one external using Mac OS 10.4.8, XCode 2.4.1 and the  
"ExternalsEnvironmentV2" provided by the newsletter
I obtained the error:
  error: `strcasestr' undeclared (first use this function)
Can anybody explain this? strstr works without a problem, and the  
external compiles in an older setting of of the XCode environment too.

 From a related problem an additional question:
LowercaseText has been deprecated, but the Unicode-savvy alternative  
CFStringLowercase with a CFMutableString seems pretty complicated.  
Does anybody know a simple method to make parameters like "AND" or  
"even" case-insensitive in an external functions?

Best regards
