#
# SYNOPSIS
#
# AX_INCLUDE_STRCASECMP
#
# DESCRIPTION
#
# This macro tries to find a header for strcasecmp() in strings.h, then
# string.h, and AC_DEFINEs AX_STRCASECMP_HEADER to the value it found. Use
# it in your source like so:
#
# #ifdef AX_STRCASECMP_HEADER
# #include AX_STRCASECMP_HEADER
# #endif
