# Oniguruma ('onig') must be first:
#
# oniguruma has some of its own implementations of POSIX regex functions,
# like regcomp() and regexec(). We use onig everywhere, for both its own
# special functions and for the POSIX replacements. This means that the
# linker needs to pick the implementations of the POSIX regex functions from
# onig, not libc.
#
# On Linux, that works out fine, since the linker sees onig on the link
# line before (implicitly) libc. However, on OS X, despite the manpage for
# ld claiming otherwise about indirect dylib dependencies, as soon as we
# include one of the libs here that pull in libSystem.B, the linker will
# pick the implementations of those functions from libc, not from onig.
# And since we've included the onig headers, which have very slightly
# different definitions for some of the key data structures, things go
# quite awry -- this manifests as infinite loops or crashes when calling
# the PHP split() function.
#
# So make sure to link onig first, so its implementations are picked.
#
# Using the generator expression to explicitly pull the path in early, otherwise
# it gets resolved later and put later in the build arguments, and makes
# hphp/test/slow/ext_preg segfault.
