 the 0-second workaround is to use g++, which doesn't have this problem.
 
 the 1-second hack-job workaround is:
 
 sealion:aoki (16)> CC -I/private/aoki/postgres/include pgtest.c /private/aoki/postgres/lib/libpq.a
 CC: "/usr/include/stdlib.h", line 169: error: two getopt()s with c linkage (1101)
 CC: "/usr/include/errno.h", line 15: error: two perror()s with c linkage (1101)
 sealion:aoki (17)> CC -D_STDLIB_INCLUDED -I/private/aoki/postgres/include pgtest.c /private/aoki/postgres/lib/libpq.a
 sealion:aoki (18)> 
 
 (the -D symbol to define depends on your stdlib.h)
 
 notice that you need to include libpq.a or the program won't be able
 to link.  (it's included in the Makefile.)
 
 the 10-second hack-job workaround is:
 
 sealion:aoki (79)> rcsdiff pg.h
 RCS file: RCS/pg.h,v
 retrieving revision 1.2
 rdiff  -r1.2 pg.h
