I did a very quick scan of the Solaris header files,
_POSIX_PTHREAD_SEMANTICS has a lot of overlap with _POSIX_C_SOURCE
but the latter definitely has more impact. From what I could gather
with the minutes I had available this morning _POSIX_PTHREAD_SEMANTICS
only affects the following functions:

readdir_r (return value)
getgrgid_r (number of params)
getgrnam_r (number of params)
getpwnam_r (types and numbers of params, return type)
getpwuid_r (types, and number of params, return type)
sigwait (number of params)
ctime_r (number of params - additional 'buflen' parameter in non-POSIX version)
asctime_r (number of params - as above)
getlogin_r (size_t vs. int for param)
ttyname_r (likewise)

(but as Mischa also said - sometimes manpages and headers conflict on
Solaris. A couple of the above may be affected by this. The number of
functions seems limited though so we may clear this up quickly as far
as libcurl is concerned)
