I tried inserting this into configure.ac/configure.in:
AC_CHECK_HEADERS(windows.h)
AC_CHECK_FUNC(GetUserName)

and get this in the config.log:
configure:17400: checking for GetUserName
configure:17457: gcc -o conftest.exe -Wall -Wpointer-arith -Wcast-align
-Wmissing-prototypes -Wmissing-declarations   conftest.c -lz  -lwsock32 >&5
C:/DOCUME~1/James/LOCALS~1/Temp/cc4Caaaa.o(.text+0x24):conftest.c:
undefined reference to `GetUserName'
C:/DOCUME~1/James/LOCALS~1/Temp/cc4Caaaa.o(.data+0x0):conftest.c:
undefined reference to `GetUserName'

Same result if replaced with GetUserNameA.  conftest.c is basically as
above.  Autoconf 2.59, by the way.

Also: 
$ objdump -x libadvapi32.a | grep GetUserName
[  7](sec  1)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 _LsaGetUserName@8
[  8](sec  5)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000
__imp__LsaGetUserName@8
[  7](sec  1)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 _GetUserNameW@8
[  8](sec  5)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000
__imp__GetUserNameW@8
[  7](sec  1)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 _GetUserNameA@8
[  8](sec  5)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000
__imp__GetUserNameA@8

Am I doing something wrong?
