The code you are trying to compile doesn't conform. POSIX (and XSI) specify certain extensions. For example, (a draft of[0]) the C standard states: All identifiers that begin with an underscore and either an uppercase letter or another underscore are always reserved for any use. Yet POSIX states: A POSIX-conforming application should ensure that the feature test macro _POSIX_C_SOURCE is defined before inclusion of any header. According to ISO C, that POSIX-mandated behavior is not allowed. dlsym(3) contains another example in its Rationale section, except for XSI instead of all POSIX systems. [0] I don't really care to purchase the actual standard, but it's probably nearly identical. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 713 440 7475 | http://crustytoothpaste.ath.cx/~bmc | My opinion only OpenPGP: RSA v4 4096b 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
