# command line syntax and $FIPSLD_CC or $CC environment variable set
# and can even be used to compile source files.

# If using an auto-tooled (autoconf/automake/libtool) project,

# simple checks. Pass-through to compiler directly if application is
# is not being linked with libcrypto, allowing auto-tooled applications
# to utilize fipsld (e.g. CC=/usr/local/ssl/bin/fipsld FIPSLD_CC=gcc
# ./configure && make). But keep in mind[!] that if certified code
# resides in a shared library, then fipsld *may not* be used and
# end-developer should not modify application configuration and build
# procedures. This is because in-core fingerprint and associated
# procedures are already embedded into and executed in shared library
# context.
