- # 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
