Helmut,
I would prefer this but was not sure which coordinate-setting option
supports this for an OpenFileGDB directory.
it seems that OpenFileGDB directory isn't recognized. you could file an
enhancement ticket for this.
a quick workaround with ogrinfo and grep. 
tested with an example fgdb downloaded somewhere from the net.
check the layers in the fgdb:
---
ogrinfo RH_SampleData.gdb

check the srs from one of the layers:

grep the srs info into a text file
----
ogrinfo RH_SampleData.gdb LRSE_Crashes -al -so | grep -A22 -B0 PROJCS >
my.prj
---
and in the GRASS start up wizard choose:
Read projection and datum terms from a Well Known Text (WKT).prj file.
all done.
