# AC_CHECK_KLIBC

# --------------
|

# Check if the user wants KLIBC support enabled. If so, set KLIBC=yes and
|
|
# fill in KLIBC_PREFIX, KLIBC_BINDIR, KLIBC_SBINDIR, KLIBC_LIBDIR and
|
|
# KLIBC_INCLUDEDIR. CC is also set to the proper klcc executable.
|
|
# NOTE: This should be called before AC_PROG_CC, and before header, function
|
|
# or type checks.
