# _BSD_SOURCE is deprecated we need to use _DEFAULT_SOURCE.
#
# That works find for more modern compilers but we have issues with:
# Centos 7, gcc 4.8.5, glibc 2.17
# Centos 6, gcc 4.4.7, glibc 2.12
#
# CentOS 6 & 7: Without -D_BSD_SOURCE, we get Warning: Implicit declaration of
# functions alloca, cfmakeraw, scandir, setlinebuf, strcasecmp, strncasecmp, and strsep.
# When a function (like strsep) returns a pointer, the compiler instead assumes a 32 bit
# int and sign extends it out to be a 64 bit pointer. Use the pointer and Kaboom!
#
# CentOS 6: We have additional problem. Without -D_POSIX_C_SOURCE=199309L, we get
# implicit declaration of function clock_gettime and the linker can't find it.
#
# It turns out that -D_GNU_SOURCE can be used instead of both of those. For more information,
# see https://www.gnu.org/software/libc/manual/html_node/Feature-Test-Macros.html
#
# Why was this not an issue before? If gcc is used without the -std=c99 option,
# it is perfectly happy with clock_gettime, strsep, etc. but with the c99 option, it no longer
# recognizes a bunch of commonly used functions. Using _GNU_SOURCE, rather than _DEFAULT_SOURCE
# solves the problem for CentOS 6 & 7. This also makes -D_XOPEN_SOURCE= unnecessary.
# I hope it doesn't break with newer versions of glibc.
#
# I also took out -Wextra because it spews out so much noise a serious problem was not noticed.
# It might go back in someday when I have more patience to clean up all the warnings.

# Try error checking -fsanitize=bounds-strict -fsanitize=leak

# This test is not detecting them for glibc 2.38 resulting in a conflict.
# Why? Are they declared in a different file or in some strange way?
#
# This is how they are declared in include/string.h:
#
# extern __typeof (strlcpy) __strlcpy;
# libc_hidden_proto (__strlcpy)
# extern __typeof (strlcat) __strlcat;
# libc_hidden_proto (__strlcat)
#
# Apparently cmake does not recognize this style.
# Keep this here for BSD type systems where it behaves as expected.
# We will need to add a hack in direwolf.h to define these if glibc version >= 2.38.
