I had looked at the source for AC_CHECK_LIB, but apparently I had glossed over the first line of its code: m4_ifval([$3], , [AH_CHECK_LIB([$1])])dnl ...although, if I'm reading correctly, I'll need to still AC_DEFINE() in /addition/ to AH_CHECK_LIB(). This probably warrants my own wrapper around both of those. Thanks so much for your help! -- Micah J.
