dnl GMP_PROG_CC_FIND([CC_LIST], [REQ_64BIT_CC])
dnl Find first working compiler in CC_LIST.
dnl If REQ_64BIT_CC is "yes", the compiler is required to be able to
dnl produce 64-bit code.
dnl NOTE: If a compiler needs any special flags for producing 64-bit code,
dnl these have to be found in shell variable `gmp_cflags64_{cc}', where `{cc}'
dnl is the name of the compiler.
dnl Set CC to the name of the first working compiler.
dnl If a 64-bit compiler is found, set CC64 to the name of the compiler and
dnl CFLAGS64 to flags to use.
dnl This macro does not test if any of the compilers found is a GNU compiler.
dnl To do this, when you have finally made up your mind on which one to use,
dnl and set CC accordingly, invoke [GMP_PROG_CC_SELECT]. That macro will
dnl also make sure that your selection of CFLAGS is valid.
