Linking to which mySQL library?

I'm trying to build a simple app under cygwin using the windows version of 
mySQL server.

If I compile with "gcc -I/cygdrive/c/mysql/include 
-L/cygdrive/c/mysql/lib/opt -lmysql myTest.c -o myTest.exe" then my program 
compiles, links and even runs, but then core dumps.  The result are very 
strange.  But while looking around on google and this mailing list, I 
learned that I should use a mySQLclient library that was compiled under a 
current cygwin.  OK I've done that (./configure --without-server;make;make 
install), but now I get errors when I try compiling my app.  gcc (actually 
ld) cannot find -lmySQL or undefined references when linking with 
-lmysqlclient.

gcc -I/usr/local/include/mysql -L/usr/lib -L/usr/local/lib/mysql 
-lmysqlclient myTest.c -o myTest.exe
/cygdrive/c/DOCUME~1/ESA3BD~1.NEW/LOCALS~1/Temp/cc25Xged.o(.text+0xdf):myTest.c:
undefined reference to `_mysql_init'
/cygdrive/c/DOCUME~1/ESA3BD~1.NEW/LOCALS~1/Temp/cc25Xged.o(.text+0x138):myTest.c
: undefined reference to `_mysql_real_connect'
/cygdrive/c/DOCUME~1/ESA3BD~1.NEW/LOCALS~1/Temp/cc25Xged.o(.text+0x1b0):myTest.c
: undefined reference to `_mysql_query'
/cygdrive/c/DOCUME~1/ESA3BD~1.NEW/LOCALS~1/Temp/cc25Xged.o(.text+0x224):myTest.c
: undefined reference to `_mysql_close'
collect2: ld returned 1 exit status
make: *** [myTest.exe] Error 1

OR

gcc -I/usr/local/include/mysql -L/usr/lib -L/usr/local/lib/mysql -lmysql 
myTest.c -o myTest.exe
/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/../../../../i686-pc-cygwin/bin/ld: 
cannot
find -lmysql
collect2: ld returned 1 exit status
make: *** [myTest.exe] Error 1

I've tried downloading a prebuilt mysql library from a german site  (Sorry I 
forgot the name).  But the same problem occurs.  I've updated my cygwin 
install with the latest stuff, but that didn't help either.

What am I doing wrong?
