Help in AC_CHECK_LIB

[madan m raj]

Hi,
Attached my configure.in script

I want to check for two libraries libIL.so  and libILU.so
so, i included the below lines in the configure.in script so as to get the 
flags -lILU and -lIL
-------------------------------------------------------------------------
#Find the DevIL library
AC_CHECK_LIB (IL, ilSaveImage, [], [
                echo -n"Error! DevIL Image Library IL not found"
                echo -n "Install DevIL-1.6.7"
                exit -1
                ])
AC_CHECK_LIB (IL, iluGetInteger, [], [
                echo -n "Error! DevIL Image Library ILU not found"
                echo -n "Install DevIL-1.6.7"
                exit -1
                ])
-------------------------------------------------------------------------
When i run the configure script i get the following warnings and errors

And at last i get an error
checking for  in -l... no
./configure: line 19585: IL,: command not found
-nError! DevIL Image Library IL not found
Install DevIL-1.6.7checking for  in -l... (cached) no
./configure: line 19663: IL,: command not found
Error! DevIL Image Library ILU not foundInstall DevIL-1.6.7


Seems AC_CHECK_LIB wont accept any library name in CAPS. Is there a way to 
solve this, or can i use any other way to check for that library.

Thanks
