Having been once again bit by something which bites me from time to
time, I thought I would just throw it out to be sure that everyone
is aware of it (kind of sharing the pain).

The following program:

	#include <pwd.h>
	#include <sys/types.h>
	main() { }

does not compile, and, indeed, produces scary errors that say:

"/usr/include/pwd.h", line 8: } missing
"/usr/include/pwd.h", line 8: (warning) old-fashioned initialization, insert =
"/usr/include/pwd.h", line 8: pw_uid undefined
"/usr/include/pwd.h", line 9: (warning) old-fashioned initialization, insert =
"/usr/include/pwd.h", line 9: pw_gid undefined
"/usr/include/pwd.h", line 16: } deleted
"/usr/include/sys/types.h", line 27: redeclaration of gid_t with different type
"/usr/include/sys/types.h", line 33: redeclaration of uid_t with different type


On the other hand, as I have to from time to time remember, the same
program, with a mere rearrangement of the include statements, will
compile and execute with nary an error.

#include <sys/types.h>
#include <pwd.h>
main() { }

Gawd, how I love working with computers!!!!
